Features Of Dow DOWANOL TPM Tripropylene Glycol Methyl Ether

  1. Low volatility with high boiling point (≈ 245 °C), enabling extended open time in coatings and inks.

  2. Excellent solvency for acrylics, alkyds, cellulose esters, and epoxy resins without excessive odor or toxicity.

  3. Low water solubility (< 1 wt%) supports phase separation control in water-reducible systems.

  4. Favorable evaporation rate profile—slower than propylene glycol methyl ether acetates but faster than dipropylene glycol methyl ether.

  5. Readily biodegradable and classified as non-hazardous for transport under UN TDG guidelines.

Typical Applications Of Dow DOWANOL TPM Tripropylene Glycol Methyl Ether

  1. Coalescing aid in architectural and industrial waterborne acrylic and vinyl acetate emulsion paints.

  2. Solvent carrier in high-solids coil coatings and automotive refinish basecoats.

  3. Viscosity reducer and flow enhancer in UV-curable flexographic and gravure inks.

  4. Performance solvent in cleaning formulations for precision electronics and optical components.

  5. Stabilizing co-solvent in pesticide and herbicide aqueous suspension concentrates (SC).
