IN-MOULD COATING COMPOSITIONS CONTAINING FUNCTIONAL GROUP TERMINATED LIQUID POLYMERS AND METHOD OF COVERING SURFACE DEFECTS OF A MOULDED THERMOPLASTIC ARTICLE THEREWITH

摘要

Fully cured reinforced moulded resins such as polyesters, polyurea urethanes, polyureas, polyurethanes, polyisocyanurates polyepoxies and polycarbonate resins can be in-mould coated to cover surface defects such as sink marks and microcracks with an improved coating composition comprising reactive liquid polymers, a vinyl monomer and certain cross-linkable unsaturated ester resins as copolymers.
