BYK-A 501

BYK A 501 is a silicone-free air release additive that is highly effective for virtually all unsaturated polyester resins and processing techniques. It is also recommended for epoxy resin systems used in advanced material formulations. BYK A 501 helps release entrapped air from resins during the manufacturing process, reducing defects. As a result, it improves mechanical properties and appearance of final products. It can be added at levels between 0.1-0.5% to resins without negatively impacting viscosity or other handling properties. BYK A 501 provides benefits such as reduced porosity, higher strength and durability for advanced material end applications. Its silicone-free nature makes it suitable for a wide range of demand industries.
