Special Features and Benefits
The additive orients itself to the coating surface and is fixed in the surface via its reactive groups by reacting with the polymer matrix. BYK-394 contains primary OH groups which react with binders, such as 2K polyurethane, alkyd/melamine, polyester/melamine, acrylate/melamine and acrylate/epoxy combinations in solvent-borne systems. The non-polar groups of the BYK-394 result in outstanding tape release. The additive improves leveling and gloss. It produces a long wave effect and prevents cratering. BYK-394 has no impact on surface tension and is thermally stable.Recommended Levels
0.2-3% 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.
