BYK-378

Solvent-free silicone surface The additive greatly increases surface slip and thereby also improves the scratch resistance. It causes a moderate to high reduction in surface tension and thereby excellent substrate wetting and a good anti-cratering effect. Fat edges (picture framing) are avoided. In matted systems it ensures a good orientation of the matting agent. BYK-378 displays a high effectiveness at low dosage and only stabilizes foam very slightly. It is widely compatible with aqueous, solvent-borne, and solvent-free systems, can be overcoated easily and does not tend to effloresce. BYK-378 is particularly recomended for automotive, industrial, leather and wood coatings.
