FEATURE AND APPLICATION
B-CAP is a phenylmethylene malonate type colorless ultraviolet light absorbent. The product's physical mesh structure allows it to absorb high-energy UV rays and act as a physical barrier, effectively blocking sunlight from the coating even in harsh climatic conditions and harsh application environments such as automotive headlamps, significantly delaying yellowing or discoloration.
