Butyl CARBITOL is a slow-evaporating, hydrophilic glycol ether with excellent coalescing and coupling power. 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. In addition, Butyl CARBITOL glycol ether offers 100% water solubility.
