Diethylene Glycol Butyl Ether

Diethylene glycol butyl ether is a high boiling glycol ether used in baking enamels to promote increased flow-out and leveling in paint films. It is also used in printing inks when very slow drying is desired. In textile dyeing, it promotes rapid, uniform penetration of dyes. This solvent is used as a coalescent in architectural paints, industrial latex paints, and as an organosol dispersant.
