产品名称：三丙二醇丁醚（DOWANOL* TPnB ）

详细说明：

DOWANOL* TPnB（三丙二醇丁醚）

Tripropylene Glycol n-Butyl Ether

Description

A very slow-evaporating, hydrophobic glycol ether withoutstanding surface tension-lowering ability; ideal where highpolymer solvency and residence time are required

Introduction

DOWANOL* TPnB (Tripropylene Glycol n-Butyl Ether) is the slowest-evaporating member of the family of DOWANOL glycol ethers. DOWANOL TPnB is a high boiling, colorless solvent with low viscosity and practically no odor. Due to its length and hydrophobic structure, DOWANOL TPnB has a high organic solubility, low water solubility, and a high boiling point. Its unique properties make it suitable for a number of water-borne resins where a powerful coalescent is needed for proper film formation. Its solvating characteristics combined with low water solubility ensure that DOWANOL TPnB wil almost completely partition into the resin phase, thus providing superior coalescence. The extremely low odor of DOWANOLTPnB makes it suitable for indoor decorative paints.
