Propylene Glycol Monomethyl Ether (PM)
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 solventhas the features to reduce the film forming temperature, promote the resins to form films and ensure the paint film quality. PM 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.
Because PM has low toxicity, it is among a few organic solvents that can be used in the adhesive of cigarette carton and packet packaging papers.
PM can also apply to household and industrial cleaner, rust remover, extraction agent and beneficiation of nonferrous metals. PM and propylene glycol n-butyl ether are important compositions of glass cleaning agent.
PM can be used as the solvent for agricultural pesticides, deactivator and emollient for livestock pesticides.

Applications of Propylene Glycol Monomethyl Ether (PM)
1-Methoxy-2-propanol is an intermediate for the herbicidal metolachlor.
As a solvent, dispersant or diluent, it is used for the coating, ink, printing and dyeing, pesticide, cellulose, acrylic and other industries. It can also be used as a fuel antifreeze, cleaning agent, extracting agent, non-ferrous metal mineralizer and the like. It can also be used as a raw material for organic synthesis.
It is mainly used as a good solvent for nitrocellulose, alkyd resin and maleic anhydride modified phenolic resin. It is used as an additive for jet fuel antifreeze and brake fluid. It is mainly used as a solvent, dispersant, diluent, fuel antifreeze, extracting agent, and the like.

Propylene glycol ethers and glycol ethers belong to the glycol ether solvents. The toxicity of propylene glycol ethers to the human body is lower than that of glycol ethers and the former belong to low-toxicity ethers. Propylene glycol methyl ether has a weak ether smell, but it does not have a strong irritating odor, making its use more extensive and safe. Since its molecular structure contains both ether and hydroxyl groups, it has excellent dissolution properties, a suitable volatilization rate, and good reactivity, thus it's widely used.
[Use 1] It's mainly used as a solvent, dispersant, diluent, fuel antifreeze, or extracting agent.
[Use 2] 1-Methoxy-2-propanol is an intermediate of the herbicide Metolachlor.
[Use 3] As a solvent, dispersant or diluent, it is used for the coating, ink, printing and dyeing, pesticide, cellulose, acrylic and other industries. It can also be used as a fuel antifreeze, cleaning agent, extracting agent, non-ferrous metal mineralizer and the like. It can also be used as a raw material for organic synthesis.
[Use 4] Propylene glycol methyl ether (107-98-2) is mainly used as a good solvent for nitrocellulose, alkyd resin and maleic anhydride modified phenolic resin, an additive for jet enolezing antifreeze and brake fluid, and a solvent for inks, textile dyes, and textile oils. Its water-based coatings are much used in the automotive industry.
[Use 5] Propylene glycol methyl ether (107-98-2) is widely used in paints and cleaners. It is specifically applied as reactive solvents for water-based coatings, reactive and coupling agents for solvent-based printing inks, solvents for ballpoint pens and pen inks, coupling agents and solvents for household and industrial cleaners, rust removers and hard surface cleaners, and solvents for agricultural pesticides. It can be mixed with propylene glycol n-butyl ether for glass cleaner formulations.
[Use 6] As a solvent, dispersant or diluent, it is used for the coating, ink, printing and dyeing, pesticide, cellulose, acrylic and other industries. It can also be used as a fuel antifreeze, cleaning agent, extracting agent, non-ferrous metal mineralizer and the like. It can also be used as a raw material for organic synthesis.
Its flammable liquid and vapor are harmful if inhaled, which can affect the central nervous system of humans. If absorbed through skins or swallowed by accident, it can also harm the entire human body. It is irritating to the skin, eyes and the respiratory tract.
