Features and Benefits

VOK?- UV 3576 reduces the surface tension capacity to a low to medium degree, and improves the wettability and leveling of the substrate. Does not increase or slightly increases surface smoothness. This product is unstable foam and has defoaming effect in some systems. The polyacrylate functional group can be cross-linked with the radiation curing system to produce a lasting effect without migration. It has good recoating property in most systems, but must be tested before use. The product has very good compatibility and will not cause fog shadow of the coating. VOK?- UV 3576 is applicable to solvent-free, solvent based and water-based systems.
