Abstract:
By use of the free-radical solution polymerization, a high adhesion acrylate resin for cathodic electrodeposion coatings was synthesized with monomers of tetrahydrofurfuryl methacrylate(THFMA), 2-hydroxyethyl methacrylate(HEMA), 2-(dimethylamino)ethyl methacrylate(DMAEMA), isobornyl methacrylate(IBOMA) and N-methylolacrylamide(NMA). Some factors that influence the coating appearance and properties of acrylic resin were studied. The results indicated that a smooth and high buid paint film could be formed at the condition of 15% THFMA, azoisobutyronitrile as initiator and about 5.8 pH bath solution, with the thickness 21. 4 μm, gloss 130. 4 and adhesion grade 0. This resin could be widely used in hardware, automobile industry, etc.
