BYK-326 additive causes only a slight reduction in the surface tension of the coating systems and has a positive effect on leveling. As a result of its broad compatibility, the high transparency of most clear coating systems is maintained and it can therefore be easily used in clear coatings for automotive, for example. In epoxy clear coatings for flooring, the additive combines high transparency, improved substrate wetting, and mild defoaming properties. Due to its special molecular structure, BYK-326 does not crystallize, even under -18 C, which makes it easy to use at low temperatures.
