| BYK 220 S |
 |
| Solution of a lower molecular weight unsaturated acidic polycarboxylic acid polyester with a polysiloxane copolymer |
 |
Wetting and dispersing additive for solvent-based and solvent-free coatings to improve pigment wetting, reduce the time required for the grinding process and stabilize the pigment dispersion.
Deflocculation of the pigments stabilizes hue and color strength and prevents looding/floating. The additive strongly reduces viscosity and improves gloss and levelling of the coatings.
BYK 220 S is able to stabilize all pigments and is preferably used in industrial paints. It increases gloss, prevents flooding/floating and reduces millbase viscosity.
BYK 220 S is distinguished by a broad compatibility in two-pack acrylic systems. |
