Applications of PMA
PMA has the lowest viscosity of entire P-series glycol ethers and their acetates, and it provides superb viscosity reduction. The remaining OH group in the glycol ether molecule is capped with an acetate group, which reduces its polarity and reduces the solvent's viscosity. The acetate group also eliminates the reactive hydrogen from the OH group found in other glycol ethers, so PMA is an excellent aprotic solvent for urethanes and other proton-sensitive systems.
PMA is a relative fast-evaporating glycol ether acetate, and it sets a performance standard in high-solids, solvent-borne systems. It provides excellent active solvency for a wide range of resin types, including acrylics, epoxies, alkyds, polyesters, and many others.
Because PMA has low toxicity, strong solvency for both polar and non-polar materials, it becomes the good substitute for E-series glycol ether acetates. It applies to dissolve various polymers in top grade coatings and inks. It is widely used in some top grade paints for car, TV, refrigerator, and airplane. In the coating industry, PMA is an indispensable auxiliary solvent to increase film strength. PMA is also a kind of raw material of glass cleaner.
PMA can also apply to the production of LCD and photoresist. It is also widely used as solvents for electronic materials.

Applications of PMA
1. Propylene Glycol Monomethyl Ether Acetate (PMA) is mainly used as a solvent for inks, paints, inks, textile dyes, and textile oils. It can also be used as a cleaning agent in the production of liquid crystal displays. It is a low-toxicity yet high-grade industrial solvent with excellent properties and has strong solvent power toward both polar and non-polar substances. It is soluble for high-grade coatings, inks, and a variety of polymers, including amino methyl esters, vinyl, polyester, cellulose acetate, alkyds, acrylics, epoxy resins and nitrocellulose prime. Propylene glycol methyl ether propionate is the best solvent for coatings and inks and is suitable for unsaturated polyesters, polyurethane resins, acrylic resins, epoxy resins, etc.
2. PMA is a multi-functional environmentally-friendly solvent. It is an indispensable auxiliary solvent in the coating industry to increase the strength of the coating film. It is widely used in the car paint, television paint, refrigerator paint, aircraft paint and other high-grade paints. The electronic grades are used as cleaning agents for LCDs and other electronic industries.
It may cause damages to the fetus.
Effects of short-term exposure: The substance irritates the eyes and the respiratory tract. Exposure to a high concentration of PMA may result in suppression of the central nervous system.
Effects of long-term or repeated exposure: The liquid degreases the skin.
