Special Features and Benefits
Due to its high surface activity, the additive accumulates on the surface of the coating. Its reactivity allows it to be incorporated into the polymer network and therefore to be anchored in the coating surface. BYK-370 improves surface slip, solvent and weather resistance, anti-blocking and reduces susceptibility to dirt. If the additive is fixed in the coating surface via its reactive groups, these properties remain present longer than with conventional, non-reactive silicones. The additive also reduces surface tension, which improves substrate wetting. It improves leveling and prevents the formation of Bénard cells.
Recommended Use: BYK-370 reacts with the resin via primary OH-groups and is primarily used in solvent-borne two-pack polyurethane systems. It may also react with the following binders: Alkyd/melamine, polyester/melamine, acrylate/melamine, self-crosslinking acrylates, epoxides. It is preferably used in wood and furniture coatings, leather coatings as well as can coatings.
