| Disperbyk-162 |
 |
| 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-162 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-162 does not influence paint binder durability.
Disperbyk-162 is used primarily in wood coatings, coil coatings, industrial finishes and for the production of pigment concentrates.
It has a slightly lower molecular weight and polarity than Disperbyk-161. |
