Application Information

Coatings Industry
BYK-012 is especially recommended as a defoamer in the preparation and application of emulsion paints and plasters within a PVC range of 30-85. The additive is free of silicones and mineral oil, and is especially suitable for VOC-free systems. It exhibits an optimal effect at the lowest dosage, is stable to acids and alkalis, and can be used in the pH range 3-12. BYK-012 can lead to turbidity and seeding in clear coatings.
Recommended Levels
0.05-0.5% 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. Sufficiently high shear forces must be applied.

 

Printing Inks and Overprint Varnishes
BYK-012 is especially recommended as a defoamer for aqueous printing inks. The additive is free of silicones and mineral oil, and exhibits an optimal effect at the lowest dosage. BYK-012 can lead to turbidity and seeding in overprint varnishes.
Recommended Levels
0.1-0.5 % 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. Sufficiently high shear forces must be applied.


Adhesives & Sealants
BYK-012 is a highly effective defoamer for all current dispersion adhesives, and inhibits foaming during both production and application. It is a particularly good defoamer for polyacrylate-based dispersion adhesives. The product is free of silicones and mineral oil, and is especially recommended for VOC-free systems. It exhibits an optimal effect at the lowest dosage, is stable to acids and alkalis, and can be used in the pH range 3-12.
