BUTYL CARBITOL (BC) 

BUTYL CARBITOL™

Diethylene Glycol Monobutyl Ether

C₄H₉(OCH₂CH₂)₂OH

Description

A slow-evaporating, hydrophilic glycol ether with excellent coalescingand coupling power.

Introduction

Butyl CARBITOL glycol ether can be considered a slower-evaporating analog of Butyl CELLOSOLVE glycol ether. It

can be used in combination with Butyl CELLOSOLVE glycol ether to lower the evaporation rate and increase the

hydrophobicity of the solvent package. Yet Butyl CARBITOL glycol ether offers 100% water solubility.
