Features and Benefits

The additive can effectively reduce the surface tension of the wet film of the coating, thereby improving the wetting of the substrate to prevent shrinkage cavity. VOK®- The SL 3550 has different performance in different polar systems. In polar systems, it has good compatibility and can be evenly distributed in the film. In nonpolar systems, there is slight incompatibility, so that it can be uniformly arranged on the coating surface.

Polar system:

It does not affect the surface energy and smoothness of the dry film, and can improve the adhesion of recoating and subsequent protective film and adhesive on its surface. VOK®- SL 3550 has wide applicability. It can be used for both primer and finish paint. At the same time, the additive can also improve the directional arrangement of matting powder

Non polar system: VOK®- 3550 can improve adhesion resistance without affecting recoating and gloss.
