Applied Composites Corp. of St. Charles, Ill., added in-mold powder coating to its sheet molding compound technology. The firm said its Enviro-Coat process uses powder coating applied directly on the tool. The coating chemically bonds to SMC during compression molding to give a surface hardness comparable to a gel coat. Applied Com-posites is patenting the technology, which it recently began using on personal watercraft hulls for an undisclosed customer.
