DOWANOL™ DPM, also known as dipropylene glycol methyl ether, is a mid-to-slow evaporating solvent with 100% water solubility. Here are some key points about this product:
Product Description: DOWANOL™ DPM is a hydrophilic solvent primarily used as a coupling agent in various solvent systems. It has a higher flash point compared to DOWANOL™ PM glycol ether, making it easier to handle, store, and ship. Its hydrophilic nature makes it suitable for preventing shocking in latex emulsion coatings and as a coupling aid in water reducible coatings and cleaning applications.
Applications:
- Coupling agent for water-based dilutable coatings
- Active solvent for solvent-based coatings
- Coupling agent and solvent in household and industrial cleaners, grease and paint removers, metal cleaners, and hard surface cleaners
- Tail solvent for solvent-based gravure and flexographic printing inks
- Primary solvent in solvent-based silk screen printing inks
- Coupling agent in solvent blends for various printing inks
- Coupling agent and solvent for vat dyeing fabrics
- Mutual solvent, coupling agent, and emollient in cosmetic formulations
- Stabilizer for agricultural herbicides
- Coalescent for floor polishes and finishes
