Basic introduction of alkyd resin

Alkyd resin Ethylene glycol phthalate resin. It is an oil-modified polyester resin formed by polycondensation of polyol, phthalic anhydride and fatty acid or oil (triglyceride). According to the number and structure of double bonds in fatty acids (or oils), they can be divided into three types: dry type, semi-dry type and non-dry type. Dry alkyd resin can be cured in air; Non-drying alkyd resin should be mixed with amino resin and cured by heating. In addition, according to the content of fatty acid (or oil) or phthalic anhydride used, it can also be divided into four kinds of alkyd resins with short, medium, long and ultra-long oil content. After curing, alkyd resin has luster and toughness, strong adhesion, good wear resistance, weather resistance and insulation.
