BYK®-3550 is a patented technology of a surface-active additive based on a silicone acrylate copolymer. It leads to a strong reduction of the surface tension of the paint system. Therefore, it improves the substrate wetting and prevents cratering. Depending on the polarity of the system, BYK®-3550 shows different properties. In polar systems the additive shows an excellent compatibility in the coating, which leads to a homogeneous distribution in the film.
