COATING METHOD FOR BLOW-MOLDED PRODUCT CONSISTING OF POLYPHENYLENE ETHER/POLYAMIDE RESIN, INTERMEDIATE COATED PRODUCT, AND COATED PRODUCT

摘要

PURPOSE:To obtain a coating film which is easily finished and has excellent appearance (smoothness, definition) without controlling the raw surface of a body to be coated by polishing or using a paste or without multilayer coating of a primer or an intermediate layer. CONSTITUTION:A primer is applied on a blow-molded product comprising polyphenylene ether/polyamide resin, then an intermediate coating having 70-90PHR pigment concn. is applied thereon, and then further a top coating material is applied. The primer consist essentially of modified polyolefin resin having -30 to -60 deg.C static glass transition temp., 85000-95000 weight-average mol.wt.(Mw), 60000-70000 number-average mol.wt.(Mn), and 1.30-1.45Mw/Mn.
