BYK-378

Solvent-free silicone surface additive for water-borne, solvent-borne, and solvent-free systems that increases surface slip and significantly reduces the surface tension at low doses. Low foam stabilisation. 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 stabilises 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.
