BYK-1781

BYK 1781 is a solvent-free silicone-based additive that acts as an effective microfoam remover in aqueous systems. BYK 1781 contains polyether-modified polydimethylsiloxane and hydrophobic particles that work together to reduce microfoam during application processes. It is highly effective even in low-VOC waterborne formulations. BYK 1781 provides outstanding protection against microfoam generated during airless or air-mix spraying without negatively impacting the finished product's transparency, gloss, or performance. The additive is solvent-free and compatible with both pigmented and clear coatings. BYK 1781 has proven defoaming capabilities that help ensure a smooth, flawless finish every time even with fast drying aqueous UV coatings. Its microfoam control properties make BYK 1781 ideal for applications where appearance and durability are top priorities.
