Coatings and Printing Inks
Special Features and Benefits
The additive reduces the surface tension in the systems to a medium level. It increases slip and improves leveling and gloss. Silicone additives prevent the formation of Bénard cells. BYK-331 also improves substrate wetting and provides anti-blocking properties.
Recommended Use
BYK-331 can be used in all aqueous, solvent-borne, and solvent-free systems and is especially recommended for automotive coatings, architectural coatings, wood coatings as well as printing inks and overprint varnishes. In two-pack polyurethane systems, it can also be added to the isocyanate hardener.
Recommended Levels
0.025-0.2% 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 incorporated during any stage of the production process, including post-addition. Thinning before incorporation may make dosing easier.
Special Note
Unlike so-called silicone oils, this additive is very user-friendly. However, before use, one should determine in test series whether foam is stabilized in certain systems and check the recoatability and crater development.
