Glycol Ether PM is the fastest evaporating solvent in the glycol ether family. This product offers very high water solubility and active solvency, and is widely used in coating and cleaning applications. It offers better viscosity reduction than heavier molecular weight glycol ethers and is particularly effective in epoxy and high solids acrylic systems.

Benefits and Applications
Coatings: Glycol Ether PM provides good solvency for a wide variety of resins including acrylic, epoxies, alkyds, polyesters, nitrocellulose and polyurethanes. Key properties for coating reformulation also include complete water miscibility and good coupling ability. Glycol Ether PM is a good substitute for E-series solvents; particularly, Ethylene glycol methyl ether and Ethylene glycol ethyl ether.
Cleaners: Low toxicity, surface tension reduction, and fast evaporation are some of the benefits of using Glycol Ether PM in cleaning formulations. It also provides good solvency for polar and non polar materials. Glycol Ether PM can also be used in combination with Dowanol PnB / Glycol Ether PnB in glass cleaning formulations.
Chemical Intermediate: Glycol Ether PM can be used in combination with other glycol ethers or solvents to custom tailor properties to meet the full requirements of the formulation. Glycol Ether PM has a very low content of primary alcohol, generally below 2%. The primary alcohol isomer is more reactive than the secondary alcohol isomer. Low primary alcohol content minimizes side product formation.
Electronics: Glycol Ether PM is used in conjunction with other solvents in the manufacture of laminates which are used to make circuit boards. Additionally, Glycol Ether PM may be used in the cleaning and removal of solder flux and masks.
Other Applications: The properties listed in the previous section also support the use of Glycol Ether PM in agricultural, cosmetic, ink, textile and adhesives products.
