In-mold dual cure coating system for fiber-reinforced composites comprises a resin curable with electromagnetic radiation and a resin curable by polycondensation or by anaerobic metal-induced polymerization

摘要

In-mold dual cure coating system comprises a resin (I) curable with electromagnetic radiation and a resin (II) curable by polycondensation or by anaerobic metal-induced polymerization. An independent claim is also included for forming coatings on fiber-reinforced composite parts by depositing a coating system as above on the inner wall of a mold and/or on a prepreg, closing the mold, performing a heat treatment to cure the prepreg and (II), giving a coated part, and curing (I) to form a top coat.
