Reaction resin flooring systems are thin layers of epoxy or polyurethane resins, which, after hardening, acquire high mechanical strength and outstanding chemical resistance. They can be applied to both new and old floors, in areas that are exposed to great mechanical or chemical wear. Epoxy floorings demonstrate excellent durability in time, keeping simultaneously the maintenance cost at the minimum. Furthermore, they form a smooth, durable, non-absorbent and easy-to-clean final surface.

Considering the market requirements for floorings of high strength and excellent level of aesthetics, ISOMAT based on its long-standing experience has developed a complete range of epoxy and polyurethane flooring systems that fulfill all modern design requirements. Besides that, ISOMAT offers the necessary technical know-how and solutions to any industrial flooring problem.

ADDITIONAL PROPERTIES

COST-EFFICIENT FLOOR RESTORATIONEpoxy floorings are a more cost-efficient solution comparing with other recommended alternatives for floor restoration, as they are easy-to-apply and can be walked on, shortly after application. Additionally, their ability to endure is longer when comparing with other floor construction alternatives.

SMOOTH OR NON-SLIP SURFACE FINISHA non-slip surface finish with different levels of slip resistance can be formed through a specific laying technique apart from the smooth finish, in areas where there is a high risk of slipping (industrial production facilities, ramps etc.).

ELECTRICAL CONDUCTIVITYIn areas there is an increasing demand to prevent the negative impact of the static electricity, such as computer rooms, printing houses, textile factories, hospitals, gas stations, power stations, ammunition stores etc. the installment of conductive epoxy flooring systems is recommended.

APPLICATION ON PARTICULARLY DIFFICULT SUBSTRATESEpoxy floorings are usually applied to clean and dry cementitious substrates that are at least 28 days old. However, by using adequate primers, they can be also applied to surfaces that are only 7 days old or appear to have rising moisture/damp problems. Moreover epoxy floorings can be installed to substrates that are contaminated with oil, provided that these surfaces have been previously treated chemically by special cleaning agents.

HYGIENE, EASY-TO-CLEANThe epoxy flooring systems of ISOMAT have been certified for their suitability for use in food process and food storage facilities, freezers, and hospitals etc., where the decision for a proper floor covering is determined by strict hygienic requirements. Furthermore, due to their smooth surface finish, they can be cleaned fast and easy.

SELECTION OF THE DESIRED COLORThe epoxy floorings are produced in a variety of colors so to meet the aesthetics' criteria of each customer and fulfill also the utility requirements of the construction site (e.g. possibility of floor marking and floor lining).

RAPID CURING - QUICK USEThe required time for the installment of an epoxy flooring system is particular short and depends on the substrate's condition and the type of the epoxy flooring that shall be applied. The applied flooring system, depending on the prevailing temperature conditions, may be walked on, already the following day upon completion of the laying works, while it can be exposed to maximum loading in a seven days time.


BASIC PROPERTIES OF POLYURETHANE FLOORINGS

RESISTANCE TO SOLAR RADIATIONThe polyurethane floorings have an excellent resistance to solar radiation (UV).

HIGH MECHANICAL STRENGTH AND ELASTICITYPolyurethane floorings offer high strength, abrasion resistance and they are used to areas that require high elasticity. Therefore, they are ideal for refrigerators and freezer rooms, industrial areas, warehouses, laboratories, hospitals, wine factories, slaughter-houses, canned food factories, car workshops etc.

EXCELLENT CHEMICAL RESISTANCE, EASY-TO-CLEANPolyurethane floorings are non-absorbent, easy-to-clean and demonstrate exceptional chemical resistance to:

Alkalis, petrochemical products, specific solvents, wastes, water, sea water and weather conditions.Dilutions of organic and inorganic acids.

RESISTANCE TO LOW AND HIGH TEMPERATUREEpoxy floorings have been exposed to extreme weather conditions without abolishing their properties, if the temperature changes gradually. They can be applied both to areas with low and high temperature (e.g. freezers and industrial production facilities).

Moisture content determination

SUBSTRATE PREPARATION1

First, a small sample of the substrate is taken for testing. Thereafter, the sample is being weighed and crumbled.

The successful installation of an epoxy flooring system starts with the proper preparation of the substrate. The substrate (industrial floor, concrete slab, cementitious screed, mosaic floor) must be free of residues that prevent bonding of the flooring layer to the substrate (such as dust, loose particles, grease etc.), dry (moisture content < 4%) and sound with sufficient strength.

Measuring the moisture content of the concrete substrate is essential in order to decide for the adequate primer. Concrete floors that are 28 days old usually have moisture content less than 4%. However, when the concrete is relatively fresh or exposed to rising moisture, then it may not be free of excess moisture. Therefore it is recommended to determine the moisture content before any application either by use of an electronic moisture meter or by the following procedure described below:

INSTALLATION PROCESS OF THE EPOXY FLOORING SYSTEMS

4-STEP INSTALLMENT1234

Substrate preparationSubstrate primingFilling up substrate irregularitiesFinal coating/sealing

In every step of the installation process it is important to use the proper tools and materials and to have good knowledge of all construction details, for ensuring a sound construction solution.

5

The moisture meter is sealed properly and shacked for 5 minutes, where, after approx. 10 minutes, the moisture content percentage of the concrete substrate is indicated.

Subsequently, the sample is put into the moisture meter together with all necessary reagents.


6

Treatment residues and dust are cleaned up with a high suction vacuum cleaner.

Grinding the surface by pellet blasting.Grinding the surface with a mosaic machine.

Substrate grinding

The concrete substrate must be prepared properly by rubbing, pellet blasting, grinding etc. in order to remove cement laitance and achieve an open textured surface, thus helping the primer penetrate deeper into the pores to induce increased anchoring and bonding of the upcoming epoxy layer to the substrate, while reaching also sufficient surface leveling. Subsequently, all dust and loose particles should be thoroughly removed by a high suction vacuum cleaner.

Substrates contaminated with oil

Surfaces contaminated with oil require thorough cleaning before being laid with epoxy floorings. At first, the floor is cleaned from the superficial dirt by hot water blasting. Then it is rubbed by pellet blasting in order to reach an open textured surface. Subsequently, the industrial cleaning agent FD-CLEAN is spread onto the surface and rubbed diligently with a hard brush, thus enabling the material to penetrate into the floor pores and emulsify the oil.After 30 minutes the emulsified oil is removed by hot water blasting. Thereafter, the floor should be primed directly with a special primer before the oil rises to the floor surface again.

Hot water blasting to remove the oil from the floor.


Metal substrates

Sand blasting onto the metal substrate for the rust removal.

Metal substrates (e.g. lofts) which shall be covered by epoxy coatings must be free of rust and any type of erosion to ensure good bonding. The treatment of these substrates shall be done by sand blasting. Thereafter, the surface should be cleaned thoroughly with a high suction vacuum cleaner.

SUBSTRATE PRIMING2Priming shall take place on the thoroughly prepared surface to ensure the proper bonding of the subsequent flooring.ISOMAT offers a wide range of primers, both solvent-based and solvent-free, dealing with all possible kinds of substrates (cementitious or metal substrates, green concrete, cementitious substrates with rising moisture or contaminated with oil). During application the primer penetrates and anchors in the pores of the substrate, thus stabilizing the substrate and acting as a bond layer between the substrate and the final coating.

Epoxy primers

DUROFLOOR-PSF2-component, solvent-free epoxy primer

In cases where the presence of solvents is not desirable (e.g. in-cabin rooms with insufficient ventilation), the use of DUROFLOOR-PSF instead of DUROPRIMER is recommended. The surface must be clean, dry and protected from rising moisture. The whole quantity of component B is added into component A. The 2 components are mixed with a low speed electric stirrer (300 rpm).

2DUROFLOOR-PSF is applied by roller, brush or spray in one layer, with consumption of 200-300 g/m depending on the substrate absorbency. The installation of the selected epoxy system follows within 24 hours after priming and when this has dried. It is classified as SR-B2,0 according to EN 13813.DUROFLOOR-PSF is supplied in packages (A+B) of 5 kg and 10 kg.

2-component epoxy primer with solvents

EPOXYPRIMER-W can be applied on dry to slightly wet substrates, without standing water. The whole quantity of component B is added into component A. The 2 components are mixed with a low speed electric stirrer (300 rpm). EPOXYPRIMER-W is applied on the substrate as it is or diluted up to 10% b.w. with water. It can be applied by brush or roller in one layer, with consumption of

2200-300 g/m depending on the substrate's absorbency. The installation of the selected epoxy system follows within 24-48 hours and only when the moisture content of the primed surface is less than 4%.It is classified as SR-B2,0 according to EN 13813.EPOXYPRIMER-W is supplied in packages (A+B) of 10 kg.


3-component, water-based epoxy primer

In case the selected epoxy floor will be installed on wet (moisture content higher than 4%) or green concrete (up to 5 days old), the substrate must be primed with the 3-component, water-based epoxy primer DUROPRIMER-W. It has the adequate diffusion coefficient to compensate the pressure created by the water vapor of moisture. At first, the whole quantity of component B is added to component A, and consequently both are poured into a clean container, where also component C is added under continuous stirring. Then the mixture is diluted 5-20% with water depending on the desired workability. DUROPRIMER-W is applied by brush or roller on the wet, with no standing water, substrate in one layer,

2with consumption of 250-300 g/m . After 48 hours and provided that the moisture content of the DUROPRIMER-W layer is less than 4%, the installation of an epoxy system may follow. If the moisture content is more than 4%, then the mentioned process shall be repeated.It is classified as SR-B2,0 according to EN 13813.DUROPRIMER-W is supplied in packages (A+B+C) of 21 kg.

EPOMAX-STUCCO

FILLING UP SURFACE IRREGULARITIES3After the primer has dried and before applying the final epoxy or polyurethane flooring, any existing substrate imperfections (cracks, holes etc.) shall be filled up in order to achieve a smooth and continuous surface. Especially in cases where the selected reaction resin flooring shall be installed in a thin layer (DUROFLOOR-R), the filling up of the surface irregularities is important for providing a smooth substrate.Patching and filling up of surface irregularities can take place with the ready-to-use epoxy putties EPOMAX-EK and EPOMAX-STUCCO especially when the area of application is limited, or by preparing a resin mortar (mixing of epoxy resin with quartz sand of particle size 0-0.4 mm). The reaction resin flooring shall be applied after the leveling material has hardened and within the time limits that are set for each type of primer (page 7-8).

Resin-mortars can be prepared by the use of the epoxy primer DUROFLOOR-PSF with addition of quartz sand, in proportion 1:2 to 1:3 by weight. Alternatively, the epoxy resins DUROFLOOR and DUROFLOOR-R can be used for this purpose, by mixing with quartz sand in proportion 1:2-1:3 and 1:1.5-1:2 b.w. If the surface has been previously primed with DUROPRIMER-W, then the same epoxy primer must be used as it is for filling up any irregularities. Finally, in case of priming with EPOXYPRIMER-W, then only the same epoxy primer can be used as a resin mortar, mixed with quartz sand in proportion 1:2 to 1:3 b.w., for filling up any irregularities.

The recent applied flooring layer should be rolled with a special spiked roller to facilitate the release of any entrapped air and avoid therewith the creation of air bubbles that may otherwise appear on the epoxy flooring surface. During application the use of spiked shoes is required. Due to its low viscosity, the mixture has self-leveling properties, while providing a smooth final surface. Due to the high fluidity of the initial mixture, in case installing DUROFLOOR onto inclined surfaces (e.g. ramps), the addition of a thickening agent in percentage 0.5% by weight is needed.

Afterwards, DUROFLOOR-R is poured onto the primed substrate.

Components A (resin) and B (hardener) are packed in two separate pots according to the predetermined mixing proportion by weight. The whole quantity of component B is added into component A. Mixing of the 2 components should take place for about 5 minutes, using a low speed electric stirrer (300 rpm). It is important to stir the mixture thoroughly near the sides and the bottom of the container in order to achieve uniform dispersion of the hardener.

Following that, it is being spread with a squeegee on the primed substrate.

The fresh layer is treated with a mohair roller to enable good anchoring and uniform distribution of material, ensuring therewith same thickness all over the floor surface. The use of spiked shoes is needed for such application.

Within 24 hours, and after the first layer of DUROFLOOR-R has dried, the second layer follows applied by the same method. 2Consumption of DUROFLOOR-R is 250-300 g/m per layer. Due to the fluidity of the product, in case of installing DUROFLOOR-R onto

inclined or vertical surfaces (e.g. stairways, ramps, base boards etc.), a thickening agent should be added in percentage 2% by weight, in order to increase the thixotropy of DUROFLOOR-R.

When the substrate contains humidity more than 4% or it’s a fresh concrete substrate, the surface should be primed with the water-based 3-component primer DUROPRIMER-W or with DUROPRIMER-SG. Its application is similar to the one of DUROFLOOR-R.

After hardening, epoxy and polyurethane floorings provide a smooth surface finish of R9 slip resistance, suitable for ordinary use. In applications where there is high danger of slipping and thus the slip resistance is requested to be higher than R9, it is possible to form an adequate slip-resistant surface finish. Primarily, the first layer of the epoxy flooring is applied and then quartz sand is broadcasted until saturation on the still fresh layer. After hardening of the layer, any loose grains are removed using a high suction vacuum cleaner. Finally, a sealing layer of DUROFLOOR (A+B), DUROFLOOR-R, DUROFLOOR 11 or DUROFLOOR-PU is applied with a roller. The slip resistance of the floor surface depends on the particle size of the quartz sand that has been used and the density of spreading.

Slip resistance

Broadcasting quartz sand onto the freshlayer of DUROFLOOR for reaching

the desired slip resistance.

Depending on the particle size of the quartz sandwhich will be used,the smooth floor surface finish

(R9) can be altered into a more slip-resistantsurface with different levels of slip resistance

(R10, R11 and R12.)

18

The slip resistance level of a floor should be selected carefully taking into consideration both the danger of slipping according to the specific site conditions and the effort in maintaining cleanliness and hygiene. The greater the granulometry of quartz sand, the greater the slip resistance, but cleaning and hygiene requirements become more difficult to maintain.

The desired level of slip resistance depends both on the particle size of the quartz sand and the density of spreading. In the following table the consumption of the sealing layer is presented in relation to the desirable level of slip resistance.

DUROFLOOR-C Conductive self-leveling epoxy flooring

19

DUROFLOOR-C is a 2-component, solvent-free, colored epoxy system. It offers permanent conductivity that prevents the build-up of static electricity on floor surfaces. Its electrical

4 6resistance is between 10 and 10 Ohm. DUROFLOOR-C provides high traffic and mechanical wear. It is resistant to organic and inorganic acids, alkalis, petroleum products, certain solvents, waste materials, water, and sea water and to weathering.

DUROFLOOR-C is used as a pourable, self-leveling coating on cement-based floors, in areas where static electricity should be avoided. It is suitable for use in computer rooms, laboratories, printing rooms, textile mills, hospitals, gas stations, electric distribution stations, ammunition storages etc.It is classified as SR-B2,0-AR0,5-IR4 according to EN 13813.It is supplied in packages (A+B) of 10 kg, with components A and B having predetermined weight proportions.

CONDUCTIVE SELF-LEVELING EPOXY FLOORING SYSTEM

APPLICATION

After hardening of the primer, special self-adhesive copper bands (conductors) should be installed on the floor in a grid formation of at least 5 m x 5 m connected with a closing circumferential cable. Then, an appropriate point of the circumferential cable of the grid formation is selected and connected to the ground. For safety reasons it is recommended to form two ground points. Afterwards, the primed surface is coated with DUROFLOOR-CV, which is applied by roller in a thin layer to cover the copper bands. (Consumption:

2approx. 200 g/m ).

Components A (resin) and B (hardener) of DUROFLOOR-C and DUROFLOOR-CV are packed in two separate containers (pots) according to the predetermined mixing proportion by weight. The whole quantity of component B is added into component A. Mixing of the 2 components should take place for about 5 minutes, using a low speed electric stirrer mixer (300 rpm). It is important to stir thoroughly the mixture near the sides and the bottom of the container in order to achieve uniform dispersion of the hardener.

DUROFLOOR-CV Conductive epoxy varnish (primer)

DUROFLOOR-CV is a 2-component, colored epoxy system with solvents. It offers strong bonding to the substrate and high conductivity that prevents the build-up of static electricity

4 on floor surfaces. Its electrical resistance is lower than 10 Ohm.

DUROFLOOR-CV is used as an intermediate layer, below the epoxy flooring DUROFLOOR-C, to generate uniform conductivity on the whole floor surface.It is classified as SR-B2,0 according to EN 13813.It is supplied in packages (A+B) of 8 kg, with components A and B having predetermined weight proportions.


TOOL CLEANINGTools used in epoxy system applications must be thoroughly cleaned with the special solvent SM-12 immediately after their use. Respectively, tools used in polyurethane system applications must be thoroughly cleaned with the special solvent SM-16.

In order to confirm that the required level of conductivity has been accomplished the measuring of the electrical resistance is recommended. The laying of DUROFLOOR-C should follow within 24 hours after the installment of DUROFLOOR-CV and when this has dried. DUROFLOOR-C is spread on the floor using a smooth trowel to a thickness of approx. 2 mm, at a consumption of approx.

21.5 kg/m /mm. The self-leveling layer should be rolled on with a special spiked roller, to avoid the formation of bubbles by helping the entrapped air to escape. The use of spiked shoes during this process is necessary. Due to its low viscosity, the mixture is self-leveling, providing a smooth final surface.

CONSTRUCTION DETAILSSealing joints

Floors extended to long and wide areas contain both construction and expansion/contraction joints. These joints, after getting properly opened along their entire length by the help of a trimmer, should be cleaned and sealed with an elastomeric material that is able to withstand any possible expansion/contraction.The same method applies also for joints around metallic frames and cattle grids.

In areas where for hygienic reasons the floor-wall intersections have to be rounded (hospitals, medical laboratories, processed food factories etc.), a skirting with the use of a polymer-modified cement-mortar (e.g DUROCRET) is installed.During the laying of the main epoxy coating, the skirting is coated with DUROFLOOR-R in order to form a continuous seamless surface with the epoxy flooring.

Connection points of epoxy flooring with other overlays

Areas that are exposed to heavy mechanical wear are the connection points of the flooring with other overlays like cement-mortars, tiles, marbles etc. In these cases the joint should be opened along the flooring sides and sealed with the same material used for coating the floor (DUROFLOOR, DUROFLOOR-R), which acts as a local reinforcement.

The mechanical properties on the surface of cement-based floors (industrial floors, concrete slabs, screeds, mosaic) can be improved cost-efficient with the use of the 2-component transparent epoxy impregnation DUROFLOOR-BI.

DUROFLOOR-BI is a 2-component, transparent epoxy system with solvents. Due to its low viscosity and its great fluidity, it can penetrate deep into the substrate by filling pores and capillaries.

Therewith the impregnated surfaces become sound and durable, and particularly resistant to abrasion, chemicals and frost. Additionally, they prove enhanced resistance to wastes, mineral oils and petroleum products. DUROFLOOR-BI is suitable for floors in parking lots, warehouses, laboratories, industries, gas stations, car repair shops etc.It is classified as SR-B2,0 according to EN 13813.It is supplied in packages (A+B) of 4 kg and 10 kg, with components A and B having the predetermined weight proportion.

FLOOR SURFACE HARDENING

“convenient, effective,simple & fast”

In cases where the floor has to be leveled and the weak outer surface layer to be removed, the substrate must be mechanically rubbed (e.g. with a mosaic machine).Components A (resin) and B (hardener) of DUROFLOOR-BI are packed in two separate containers (pots), having the correct predetermined mixing proportion by weight. The whole quantity of component B is added into component A. Mixing of the 2 components should take place for about 5 minutes, using a low speed electric stirrer (300 rpm). DUROFLOOR-BI is applied by brush, roller or spray in 1-2 layers, according to the substrate's absorbency. The second layer of the impregnation follows 15 min after the first one has been applied.
