German technical background VOK-W975 Wetting dispersant Prevent pigment re flocculation replaces BYK-W975

German technical background VOK ®- Disper W975 Wetting Dispersant

For organic and inorganic pigments

VOK ®- Disper W975 is used as a wetting and dispersing agent in the pigment slurry of thermosetting resin. It improves the pigment wetting and shortens the dispersion time, prevents the pigment from re flocculation, thus stabilizing the tinting power and color tone of the finished slurry.
