Application:
Propylene glycol methyl ether acetate: It is a high-performance low toxicity advanced industrial solvent with strong solubility for both polar and non-polar substances. It is suitable as a solvent for various polymers in high-end coatings and inks, including amino methyl esters, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin, and nitrocellulose. It can also be used as a solvent for paints, inks, textile dyes, and textile oils.
Dipropylene glycol methyl ether acetate: low odor, low viscosity, strong solubility, moderate evaporation rate, and good coupling ability. It has good solubility for most resins such as acrylic resin, epoxy resin, alkyd resin, and polyester resin. It is mainly used for solvent based coatings and screen printing inks, and can also be used to dissolve special resins. It is widely used in the essence and fragrance industry.
