Firstly,hydroxyl terminal waterborne polyester resin( HWPR) is prepared by melting process using neopentyl glcol( NPG),trimethylol propane( TMP),isophthalic acid( IPA),adipic acid( AA) and trimellitic anhydride( TMA) as main raw materials,and then reacts with methyl triethoxysilane( MTES) to obtain silicone-modified waterborne polyester resin( Si-HWPR).Finally,silicone modified waterborne polyester baking paint is formed by mixing Si-HWPR with high methylated melamine resin,a curing agent.The structure and ...
