ELECTRONIC GRADE PROPYLENE GLYCOL MONOMETHYL ETHER ACETATE
Paint chemicals 2025-03-21
Molecular formula is C6H12O3. colorless hygroscopic liquid with special odor, it is a non-polluting solvent with multi-functional groups. It is mainly used as solvent for ink, paint, ink, textile dyes and textile oils. After purification of high-purity electronic grade specifications are used in semiconductor, liquid crystal display production photoresist solvent, cleaning agent. Flammable, may form explosive vapor/air mixtures above 42°C.
