German Technical Background VOK-W965 Wetting Dispersant Improve Surface Grinding Performance Replaces BYK-W965
German technical background VOK ®- Disper W965 Wetting Dispersant
Wetting dispersant for unsaturated polyester resin
VOK ®- Disper W965 is particularly useful for wetting and dispersing fillers such as aluminum hydroxide, calcium carbonate, calcium sulfate and talcum powder, VOK ®- Disper W965 is widely used in unsaturated polyester putty compounds. It reduces the viscosity of filled polyester compounds and improves their fluidity, so it is possible to achieve a higher filler filling volume. The amount of filler added in the putty improves the polishing performance of the cured putty surface.
