| Disperbyk-166 |
 |
| 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®-166 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-166 does not influence paint binder durability.
Disperbyk-166 is an addition to the Disperbyk-161/162/163 family and should be used for difficult to stabilize pigments (such as DPP-types).
The molecular weight of Disperbyk-166 is similar to that of Disperbyk-161, but it is more polar.
Pigment grinds with Disperbyk-166 are absolutely compatible with pigment grinds containing Disperbyk-160/161/162/163/164.
This additive is mainly used for automotive coatings. |
