BYK-397

BYK-397 is a low-polarity additive that is characterized by highly balanced compatibility in coatings and perfect orientation toward the coating surface. This has two effects: Firstly, the additive offers outstanding leveling properties, and secondly, it provides a spontaneous defoaming effect, even at a low additive dosage. The surface tension of the coating is only slightly reduced, thereby ensuring that the recoatability and good intercoat adhesion are retained. Furthermore, BYK-397 can be used both in pigmented systems as well as in clearcoats, and does not cause haze or turbidity. It can also be used in high-gloss coatings. BYK-397 is suitable for systems with low film thickness and systems with high film thickness. It is thermally stable and does not cause yellowing at high baking temperatures.
