W´Add 720 is a modified polydimethyl siloxane for the use in aqueous and solvent based anti graffiti coatings.
The addition of 1.5 - 3.0% W´Add 720 (based on total formulation) in solvent based and aqueous 2 pack-PUR-systems increases the surface smoothness substantially. The content of functional curable groups leads to an anchorage in the paint surface and produces a long lasting effect against water as well as grease and oil containing substances, dirt, detergents, felt tips, spray lacquers etc..
The cleanability of the coating (e.g. with special anti graffiti removers) will be increased.
When used in clear lacquers W´Add 720 could lead to turbidity but normally this has no negative effect on gloss and/or efficiency.
