Application

Application

  1. 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.

  2. 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.

  3. Because PMA has low toxicity, strong solvency for both polar and non-polar materials, it becomes good substitute of 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 coating industry, PMA is a indispensible auxiliary solvent to increase film strength. PMA is also a kind of raw material of glass cleaner.
