Coating composition capable of giving thick coating film

摘要: PURPOSE: To provide the titled composition for automobile use, having excellent abrasion resistance to protect a car from damages in washing, and gloss, by compounding an OH-containing acrylic resin with reactive hardener alcoholic colloidal silica at specific ratios. CONSTITUTION: The objective is obtained (A) containing 0.2W3mol of hydroxyl groups per 1,000g nonvolatile component (e.g. organic solvent solution copolymer derived monomer one group radically polymerizable vinyl molecule free blocked polyisocyanate resin) (C) 0.5W50wt% (based on total component) 1W5C monohydric alcohol sol). EFFECT: Applicable as thick coating film vertical plane well horizontal plane. COPYRIGHT: (C)1985,JPO&Japio
