WHY OUR SYSTEM

ORGANISATION• The DOS System is simple organised system using a

storage rack, no time is wasted searching for prod-ucts and you gain a quick overview of remainingstock.

• The storage rack enables upside down storage ofbottles enabling the content to be instantly ready todispense without shaking or squeezing.

• You have a capacity for 14 bottles which means highused products can be double stocked.

PRACTICALITY• The practical user-friendly one-handed application

with the easy to operate twist lock means you alwayshave one hand free to hold material or tools.

• The measuring head has a self-cleaning closure sys-tem, this is to make sure that no residual product re-mains in the nozzle.

• The products are silicone free, making them unlim-ited use in automotive environments.

PRECISENESS• The bottle gives you an infinitely variable dispensing

system, quantity can be dispensed based on appli-cation, and this minimises costs of product used andsaves the customer money.

• The accordion bottle is used for high viscosity materi-als which minimises costs because bottle can be vir-tually completely evacuated.

Würth DOS SystemThe Würth DOS system is an innovative one handed measuring system, which represents Würth quality whilst alwayslooking into further development. It is a proven and stylish system, which clearly demonstrates its organisation, prac-ticality and preciseness qualities whilst having valued content.

Würth DOS products are used for the locking and sealing of closely mating metal parts in applications such aslocking threads, retaining bearings, flange and gasket seals and sealing pipe work. They are designed to curewhen oxygen is absent (anaerobic). These products are formulated to give different levels of hardness and re-activity on curing.

PRODUCT • The products are used in the automotive, metal, construction and electronic industries

• The material is applied in a liquid state directly onto an oil and dust free surface

• The cleaner the surface, the stronger the bond

• These adhesives cure in an anaerobic environment, i.e. the adhesive only hardens when not exposed to oxygenfor this reason, the containers are only 3/4 full.

• The curing speed is influenced by the catalytic effect of metal as well as the width of the gap. The more passivethe material and the wider the gap, the slower the adhesive will cure. These passive materials are: Nickel, zinc,tin, precious metals, aluminium with a low Cu and /or manganese content, high-alloy steel, oxide or chromate lay-ers, plastics, glass and ceramic materials

• The product is resistant to a wide variety of lyes, gases, solvents, oils and fuels.
