| Disperbyk-170 |
 |
| Solution of a High molecular weight block copolymer with pigment affinic groups |
 |
High molecular weight wetting and dispersing additive for solvent-based coatings.
It prevents reflocculation of pigments through steric hindrance and therefore stabilizes the color strength and hue of pigments in paints and pigment concentrates.
Disperbyk-170 improves pigment wetting, reduces the time required for the grinding process and improves gloss and levelling.
Viscosity is reduced and thixotropy is avoided.
The additive charges the pigments equally and therefore prevents possible co-flocculation of different pigments.
Due to its high molecular weight and resin-like structure, Disperbyk-170 does not influence paint binder durability.
Disperbyk-170 has an extremely high molecular weight (similar to Disperbyk-161) and consequentially gives excellent stabilization of inorganic and organic pigments.
It is especially suitable for acid-catalyzed polyester/melamine topcoats and PVdF systems such as coil coatings, automotive finishes and general industrial coatings, because it does not interact with the acid catalyst. |
