 |
Silicone additive to improve surface properties in all solvent-based, solvent-free and aqueous coatings.
BYK-331 reduces surface tension and therefore provides better substrate wetting.
At the same time surface slip is increased and anti-blocking properties are improved.
Formation of Beard cells is avoided, levelling and gloss are improved.
In two-packpolyurethane systems, it can also be added to the isocyanate hardener. |
