BYK
Silicone for coatings
The BYK-3550 is a silicone based on macromeres and polyacrylates that significantly reduces surface tension in the coating system, improving substrate wetting and preventing crater formation.
This additive exhibits different properties depending on the polarity of the system. In coatings with high polarity, silicon provides good anti-crater properties without increasing surface slippage.
However, in non-polar systems conventional silicon additives have negative impacts. However, the BYK 3550 provides outstanding repainting in these systems and excellent flow in relation to different anti-lock properties.
