| BYK-A 501 |
 |
| Solution of foam destroying polymers, silicone-free |
 |
Silicone-free defoamer to prevent foam formation during production, filling, and application of solvent-based and solvent-free coatings.
BYK-A 501 displays spontaneous defoaming properties and demonstrates no negative influence on intercoat adhesion when overcoated.
BYK-A 501 is designed for use in unsaturated polyesters, acrylic/vinylacetate-combinations and oil-free polyesters.
Additionally, BYK-A 501 acts as an air release and levelling additive. |
