BYK®-019 is a solution of a polyether modified polydimethylsiloxane. BYK-019 is recommended for aqueous coatings based on polyurethane dispersions and polyurethane /acrylic combinations. It is also effective for defoaming pigment concentrate formulations. To reduce microfoam, a combination of BYK-019 with BYK-024 in a ratio of 3:2 has been shown to give excellent results.
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.
