DOWANOL PNP GLYCOL ETHER - DOW

DOWANOL PNP GLYCOL ETHER - DOW is a fast-evaporating glycol ether with an excellent balance of hydrophilic and hydrophobic character along with outstanding soil removal and coupling properties. It offers an excellent balance between hydrophilic and hydrophobic character; it is our most hydrophobic glycol ether that still maintains complete water solubility. This is our P-series product that most closely matches the properties of Butyl CELLOSOLVE™ glycol ether. Its primary use is in cleaning products, where its fast evaporation rate and excellent ability to solubilize organic soils makes it useful in a wide variety of formulation systems. It is an excellent choice in glass cleaners and all-purpose cleaners, especially in combination with selected PM-series glycol ethers.
