DOWANOL™ PPh
Propylene Glycol Phenyl Ether

Description

A slow-evaporating, very hydrophobic glycol ether ideal in coalescing and carrier solvent applications.

Introduction

DOWANOL PPh glycol ether is a slow evaporating, very hydrophobic glycol ether — more hydrophobic than would be expected based simply on its molecular weight. This product has low odor. With its aromatic structure, DOWANOL PPh glycol ether is an excellent match for phenolic coatings and linings; it is also an excellent coalescent for acrylic-based latexes. DOWANOL PPh glycol ether is also used extensively in dyeing applications, where it can function as both a dye solubilizer and as a dye carrier. DOWANOL PPh has superior viscosity reduction properties in metalworking fluids.
