Coatings Industry
Special Features and Benefits
BYK-025 is recommended for non-pigmented acrylate/polyurethane and polyurethane high gloss emulsion systems. The defoamer is especially recommend for curtain coating application, since it is very easy to incorporate and allows optimizing dosage by post-addition while the paint is running on the curtain coater.
Recommended Levels
0.1-1.5 % additive (as supplied) based upon total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
The additive can be added at any time during production.The amount of defoamer used is often divided (by adding 2/3 into the millbase and 1/3 into the let-down or finished product).
Adhesives
Special Features and Benefits
BYK-025 is a highly compatible defoamer and is specifically recommended for sensitive aqueous adhesive systems.
Recommended Levels
0.05-1 % additive (as supplied) based upon total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
The additive can be added at any time during production. Since the defoamer can be easily incorporated, it allows optimal dosage by post addition.
