DOWANOL TPM GLYCOL ETHER - DOW

DOWANOL TPM GLYCOL ETHER - DOW is a hydrophilic, slow-evaporating glycol ether with an excellent active solvency and coupling power. This is an ideal choice when high polymer solvency and extended system residence time are required. It can maintain rheological properties over time in products such as stamp pads and ball point pen inks. Its high boiling and flash points make it an excellent choice for use in oven cleaners, and as a tailing solvent in high-solids, solvent-based coatings.
