Substrate Materials

Polycarbonate (PC)

One part water soakable Anti-Fog Coating. When cured with heat, will render a surface permanently fog-free. Suitable for dip, flow, and spin application. Coating is ready to use with no solvent addition required. Vistex is a cross-linked hydrophilic polymer composition that causes condensed water droplets to spread evenly. Coating will not saturate and fail under very hu-mid conditions, as will many other anti-fog materials. Highly durable when wet, anti-fog prop-erties are retained even after repeated washing with commer-cial glass and lens cleaners.

Application & Cure Requirements Recommended dry coating thickness is 0.11 to 0.22 mils (3 to 6 µ). Thinner coatings will be less resistant to abrasion and may have reduced anti-fog properties. Theoretical cover-age ranges from 900 to 1800 sq. ft. per gallon (22 to 44 M2 per ltr). Baking should begin as quickly as possible after the coating application; and while the coating is still wet. Coated parts should be allowed to drain for no longer than 20 min. Draining or air dry time of 5-10 minutes is preferred. Longer air dry times may prevent the coating from curing completely, especially if the ambient humidity is above 70% RH. High humidity may also contribute to haze, notable at the top of coated parts. Proper curing is essential to the coatings per-formance. The use of temperature indicating labels is strongly recommended. A minimum surface temperature of 248°F (120°C) is neces-sary for proper curing to take place. Curing at 130°C is strongly recommended. Complete cure requires:

It is important to cure Vistex coatings at the highest temperature the substrate will with-stand. Coatings cured at lower temperatures will not be as hard as coatings cured at higher temperatures. Cure time depends on a number of factors, including the mass of the coated article and the efficiency of the oven. A yellow discoloration indicates the coating has been over-cured and exposure time should be reduced. Alternative-ly, coated parts may be dried for 10 min. at a low temperature (e.g. 140°F/60°C) and then cured at higher temperatures. This is particu-larly useful for lenses which are highly stressed.

H E A LT H & S A F E T Y I N F O R M A T I O N Before using this product, read and understand the Safety Data Sheet, SDS, which provides infor-mation on health, physical, and environmental hazards, handling precautions and first aid recom-mendations. For a copy of an SDS, contact an FSICT sales or customer service representative. HANDLING & SAFETY PRECAUTIONS Avoid contact with skin and eyes. Do not take internally. Observe proper industrial hygiene, includ-ing splash goggles and impervious gloves. Provide adequate ventila-tion. Avoid solution contact with strong acids or alkalis. Dispose of solution and clean-up wash water in accordance with local, state and federal regulations. Shipping regulations for flammable substance are applicable. Consult the SDS for further information, or call FSI Coating Technologies Inc. at 1-949-540-1140.

Flow, dip and roller application techniques are all suitable. For spraying, Vistex solution should be diluted to 5 or 6% NV. The higher dilution ratio is offset by flash evaporation form atomized droplets. A good dilution solvent mixture contains 67% isopropyl alcohol (IPA) and 33% distilled or demineralized water. Small amounts of butanol or diacetone alcohol can be used to prevent humidity blush and to slow evaporation so droplets have a chance to flow together. At 6% N.V, do not exceed 30% total organic solvent. A white hazy precipitate indicates the system does not have enough water to keep all materials in solution. Be careful to prevent contamination by grease, oil and other lubricants, especially silicones.

Substrates The preferred substrate is polycarbonate. Excellent wetting, flow and adhesion are usual-ly obtained without the use of primers or addi-tives. Some substrates such as glass, metal, and metalized plastics may require pre-treatment with a primer solution to promote adhesion. Articles to be coated must be free of surface contamination. (e.g. from oils, mold releases and masking residues). Plastics other than polycarbonate can be coated as long as the particular material can tolerate baking temperature of 266°F (130°C) or higher.

The coating and curing operations may reduce impact resistance of polycarbonate and other plastics. Usually this effect is minor. However, it is essential that comparative tests be includ-ed in any evaluation program.

Coated articles may be subsequently drape formed or hot pressed. However, the coating will crack if elongation exceeds 25% to 30%; as in vacuum forming operations, and anti-fog will be lost in those areas. The coating will tolerate brief exposure to temperatures over 350°F (175°C) and exhibits long term stability at 140°F (60°C).

Maintenance & Care Properly cured Vistex coatings will usually out-last the coated item. Resistance to oil based stains is excellent. Water soluble stains may penetratethe coating if left in contact with it for an extended period of time. Grease and oils will contaminate the surface and impair anti-fog effectiveness. These contaminants can be removed with a strong grease cutting deter-gent such as Top Job®, Fantastik® or Formula 409®. Coated articles should be cleaned regu-larly to prevent accumulation of oily deposits. Avoid using abrasive cleaners or pads. It is normal for the coating to pass through a tacky phase as it dries. To clean, wipe with wet cloth or paper towel and allow to dry. Do not try to rub to dryness. This will leave smudges and will necessitate cleaning again.

Scratch Resistance The scratch resistance of Vistex is superior to untreated polycarbonate; however it is not designed to perform like silicone or acrylic hard coats. Superficial scratches caused by finger-nails, harsh fabrics or other abrasive materials, such as Velcro, can be permanently healed by wiping with a damp cloth or by breathing on the scratched coated surface. The coating will not crack, peel or flake as it ages.

Chemical Resistance Vistex coatings are unaffected by brief exposure to: Methanol, ethanol, isopropanol, acetone, methyl ethyl ketone, diacetone alcohol, toluene, hexane, gasoline, glycol esters, ethyl acetate, and ammonium hydroxide solution.

Avoid exposure to strong acids and alkalis. Alcohols will soften the coating and make it more susceptible to gouging by hard objects. After drying, normal hardness will return.

Clean-Up & Removal Equipment is best cleaned with soap and water or a water and isopropanol solution. Removal of dried coatings may require a strong polar solvent such as N-methyl pyrrolidone or diace-tone alcohol. When fully cured, it may be im-possible to remove the coating except by me-chanical abrasion.

Shelf-Life Vistex solutions will remain usable for six months or longer if stored at 77°F (25°C). A light, fluffy precipitate may develop on stand-ing, and this can produce slight haze or particu-late contamination in cured coatings. Usually this does not become apparent for several months at least. If it does appear, precipitate should be re-dissolved by warming briefly to about 150°F (65°C).

Test old solutions before use. Any mixture that has become milky or contains white insoluble precipitate must be discarded.

Suggested Tests for Vistex Materials Degree of Cure: Pencil hardness when wet should be 5B or greater. Cure can be evaluated by scrubbing with a white Scotch Brite pad (3M Co.) and water. After 25 rubs, the coating may be scratched considerably, but should not be abraded from the substrate. If the coating turns milky or smears when rubbed with a wet cloth, it is grossly under cured or has been improperly formulated.

Coatings that are less them 3 microns (0.12 mils) thick will have less resistance to abrasion and may seem to be under cured. Such coatings usually have an iridescent (rainbow) appearance in reflected light.

Suggested Tests (Cont.) Anti-Fog Test #1: The test surface is immersed in distilled or deionized water for 1 hour. It is then placed faced down over a con-tainer of warm water (122°F/50°C) so as to completely cover the opening. Vistex coatings may exhibit a ring of condensation as the coating hydrates, but will remain clear indefi-nitely thereafter. When sufficient moisture has condensed to form large water drops, the test is complete. Anti-Fog Test#2: The test surface is immersed in distilled or de-ionized water for at least 24 hours, removed and allowed to dry at least 1 hour. The sample is then cooled in a refrigerator to approximately 70°F (4°C) and 70% to 80% relative humidity. Materials coated with Vistex will remain free of fog indefinitely.

Untreated plastics or glass will fog in a few seconds. Inferior anti-fog coatings may fog imme-diately, or remain clear for a short time until they become saturated.
