PM Solvent
PM GLYCOL ETHER Fast-evaporating, hydrophilic glycol ether with excellent active solvency and coupling abilities for coatings, inks and cleaners
Description:
PM glycol ether is the fastest evaporating solvent in the DOWANOL™ 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.
|
Used in:
- Solvent-based coatings
- Solvent-based gravure and flexographic printing inks
- Solvent blends for water-based gravure, flexographic, and silk screen printing inks
- Ball point and felt tip writing pen inks
- Household and industrial cleaners, rust removers, and hard surface cleaners
|
Advantages:
- Excellent active solvency
- Very fast evaporation rate
- Low viscosity
- High dilution ratio
- Low surface tension
