Whatsapp Order

Methoxy Propyl Acetate (PMA) is a clear, colorless liquid solvent with a mild fruity odor. It is an ester derived from methoxy propanol and acetic acid, widely used in coatings, inks, adhesives, and cleaning products due to its excellent solvency, moderate evaporation rate, and good compatibility with various resins. PMA offers low volatility and strong solvency for a broad range of materials, making it ideal for industrial and commercial applications.
