BYK®-1770 is a polyether modified polydimethylsiloxane. This product is very efficient in aqueous thick layer systems based on acrylic and PU-acrylics which are applied by airless / airmix. It prevents formation of microfoam and is suitable for pigmented systems and clear coats. The addition of BYK-1770 has no negative influence on turbidity (transparency) and gloss in high gloss systems. The additive is solvent-free.
BYK has an established history of innovation such as being the first additive manufacturer to begin using Controlled Polymerization Technology (CPT), launching the first rheology-modified wax emulsion, and being one of the first companies to use nanotechnology for improving Coatings properties. BYK invests approximately 7.5% of its earnings in R&D—three times more than the industry average.
