SURFADIOLS 245

Silicone-based Substrate Wetting Agent

SURFADIOLS 245

(Alternative to TEGO-245)

SURFADIOLS 245 is a highly active siloxane-based substrate wetting additive. It shows very good substrate wetting properties on difficult substrates like wood and plastic. It is highly compatible and

recommended for waterborne and solventborne coatings. It does not affect the adhesion between layers and recoatability.
