Application:
PMA is excellent industrial solvent with low toxicity and has strong solubility for polar and non-polar substance, which can be used for advanced paint, printing ink as well as some other polymers, including amido, methyl ester, ethyl, polyester, cellulose acetate, glycol acid resin, crylic acid resin, epoxy resin and nitrocellulose, etc. It can also applied as solvent of paint, ink, textile dyestuff and spinning oil.
With low odor, low viscosity, good solubility, moderate evaporation rate and good coupling ability, DPMA can dissolve most of resin like: acrylic resin, epoxy resin, alkyd resin and polyester resin. It is mainly used in solvent based paint and silk screen printing ink. Besides, it can dissolve special resin, and be widely used in flavor and fragrance industries. |
