BYK Additives & Instruments (Wesel, Germany) has launched BYK®-3550, a surface-active additive that incorporates both acrylate and silicone characteristics to improve coating application properties.
According to the company, the silicone macromer-modified polyacrylate reduces surface tension in high-polarity coatings to improve leveling, and the silicone part provides good anti-crater properties without increasing surface slip. The additive also improves recoating properties.
The main applications for the product are industrial, architectural, automotive, and wood coatings.
BYK Additives & Instruments is part of specialty chemical maker Altana.
