Eastman PM Acetate Solvent
Categories: Fluid; Solvent

Material Notes: CAS No. 108-65-6

Product Description: Eastman™ PM Acetate (Propylene Glycol Monomethyl Ether Acetate) is a slow evaporating solvent with both ether and ester functional groups. It is a colorless liquid with a mild odor. Eastman™ PM Acetate is an excellent solvent for many commonly used coating polymers, including cellulose acetate butyrate, nitrocellulose, epoxy resins, acrylic copolymers, and phenoxy resins. The combination of slow evaporation rate and good solvent activity makes Eastman™ PM acetate an effective retarder solvent for use in lacquers, thinners, and baking enamels. It is supplied as a urethane grade solvent.
