DOWANOL™ PPh Glycol Ether

DOWANOL™ PPh is a slow evaporating, very hydrophobic glycol ether. With its aromatic structure, this product is an excellent match for phenolic coatings and linings; it is also an excellent coalescent for acrylic-based latexes. DOWANOL PPh also offers excellent performance benefits as a dye solubilizer and carrier in dyeing applications, and it has superior viscosity reduction properties in metalworking fluids.

Used in:

  • Water-based architectural and industrial coatings
  • Textile dyes
  • Inks in ball point and felt tip pens, stamp pads, and textile printing pastes
  • Paint removers

Advantages:

  • Coalescing ability
  • Powerful solvency
  • High dilution ratio
  • Low evaporation rate
  • Low viscosity
