Diethylene Glycol Monobutyl Ether/ Butyl Carbitol
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.
Butyl CARBITOL solvent is useful in lacquers, dopes and stamp-pad and printing inks that require a solvent with an
extremely low rate of evaporation. This glycol ether is incorporated in high-bake enamels to contribute desirable
flow and gloss characteristics. Butyl CARBITOL solvent is a dye solvent used to promote rapid and uniform ink
penetration for printing box-board and similar materials.
Butyl CARBITOL solvent serves as a mutual solvent for soaps, oils and water and as a component of liquid cleaners,
“soluble” oils and textile oils. It has found increased use in cleaning formulations because of its good solvency for
greasy soils and waxes.
Butyl CARBITOL solvent is used as a solvent in formulating aids for latex paints and as a dispersant for vinyl
chloride resins used in organosols. It is a diluent for hydraulic brake fluids and an intermediate in the manufacture
• Latex coalescent in water-based architectural and industrial coatings.
