BYK Additives & Instruments: BYK®-3550 is a surface-active additive based on BYK-developed and patented macromer technology. Combining acrylate and silicone properties, BYK-3550 exhibits different properties depending on the polarity of the system. In coatings with high polarity, the silicone provides good anti-crater properties without increasing the surface slip. In non-polar systems, the long acrylate chain provides outstanding recoatability and excellent flow with distinctive anti-blocking properties.
