German technical background VOK-WS Wetting dispersant Prevent floating color and hairiness replaces BYK-WS

German technical background VOK ®- Disper WS Wetting Dispersant

Improved pigment wetting A wetting and dispersing agent that reduces the time required for the grinding process and stabilizes pigment dispersion. It prevents floating and blooming and improves luster. VOK ®- Disper WS is a deflocculating agent that can prevent color floating and blooming. It contains polysiloxane copolymers, which help prevent pigment separation and especially prevent the formation of Bernard dimples and pigment streaks.
