Propylene glycol methyl ether acetate

Propylene Glycol Methyl Ether Acetate(PGMEA) Product Introduction and Applications

I. Basic Properties

1. Physical Properties

   • Colorless or pale yellow transparent liquid with a characteristic ether-like odor; density approximately 0.970 g/mL (25°C), boiling point 145-146°C at atmospheric pressure (233°C under reduced pressure), freezing point as low as -87°C;
   • Flash point 43°C, flammable, slightly soluble in water (19.8 g/L at 25°C), readily soluble in alcohols, ethers, and other organic solvents.

2. Chemical Properties

   • Contains both non-polar and polar functional groups, exhibits strong solubility for resins, oils, etc., moderate evaporation rate, and good stability;
   • Low toxicity and environmentally friendly (oral LD50 in rats not specified, but industrial grade certified as low hazard).

II. Core Applications

1. Coating and Ink Industry

• High-end Coating Solvent:
• Acts as a leveling agent and diluent, enhancing the coating properties and adhesion of automotive paints, aircraft paints, and appliance coatings; widely used in epoxy resin, polyurethane, and other systems;
• Improves fluidity in ink production, used in printing inks and textile dyes.

• 2. Electronics Industry

  • Liquid Crystal Display (LCD) Cleaning Agent: Used for photoresist dilution, photoresist removal, and semiconductor etching processes;
  • Photoresist Auxiliary Agent: Serves as a developer and stripper in TFT-LCD manufacturing.

  3. Chemical and Manufacturing Industry

  • Resin Processing: Dissolves nitrocellulose, alkyd resins, etc., used in adhesives and plastic plasticizers;
  • Textile and Leather: Functions as a solvent for textile oils and leather tanning agents, enhancing flexibility and gloss.

  4. Other Fields

  • Fuel anti-freeze additive, metal beneficiation agent;
  • Environmentally friendly alternative solvent, gradually replacing highly toxic traditional solvents.
