Audited Supplier Propylene glycol methyl ether acetate (PGMEA), also called propylene glycol monomethyl ether acetate, with molecular formula C6H12O3, is a colorless and hygroscopic liquid with special odor, a non-public solvent with polyfunctional groups. It is mainly used as a solvent for ink, paint, ink, textile dyes, textile oil, and also used as a cleaning agent in the production of liquid crystal display. Flammable, may form explosive vapor/air mixture at higher than 42°C.
It is a high grade industrial solvent with excellent performance and low toxicity, and has strong solvency ability for both polar and non-polar substances. It is suitable for high-grade coatings and inks of various polymers, including aminomethyl esters, vinyl, polyester, cellulose acetate, alkyd resins, acrylic resins, epoxy resins and nitrocellulose, etc. Among them. Propylene glycol methyl ether propionate is the best solvent for coatings and inks, suitable for unsaturated polyester, polyurethane type resins, acrylic resins, epoxy resins, etc.
