BYK-378

BYK 378 is a solvent-free silicone surface additive that increases surface slip and significantly reduces the surface tension at low doses. It features low foam stabilization. BYK 378 significantly increases surface slip, thus improving scratch resistance in the process. It leads to a moderate to severe reduction in surface tension, which in turn results in excellent substrate wetting and good anti-crater effect. This prevents the so called "picture framing" effect. BYK 378 is highly effective at low doses and displays low foam stabilization. It broad compatibility in aqueous, solvent-borne, and solvent-free systems, can easily be recoated, and does not tend to bloom.
