Propylene Glycol Monomethyl Ether (PM)

Product Description

Applications of Propylene Glycol Monomethyl Ether (PM)
PM is a kind of solvent having the lowest boiling point and the fastest evaporating rate among the P-series solvents. It has both hydrophobic covalent ether bond and hydrophilic hydroxy group in its molecular structure. So it has high solubility to both oily and aqueous resins. Its hydroxy group still has reactivity to enable it to act as the chemical intermediate.

In the paint, PM has the features to reduce the film forming temperature, promote the resins to form films and ensure the paint film quality. PM solvent is a good coupling agent in solvent blends. It can replace alcohols solvent in dissolving dyes. During the production of inks, PM appears in some formulas to modify the hydrophilicity of inks to decrease inks' toxicity, improve operation environment and upgrade printing quality. It applies to flexographic and silk screen printing inks to control the evaporating speed and adjust the viscosity of the systems.

PM has superb viscosity reduction ability. It manifests the ability particularly in epoxy and high solids acrylic systems. In new type brake fluids of the motor vehicle, PM is used as the viscosity modifier. Because the mixture of PM and water can reduce the freezing point, PM is also used in antifreezing solution for the radiator.
