Butyl di glycol acetate (also known as BDGA, diethylene glycol monobutyl ether acetate, butyl diethoxol acetate, and butyl diglycol) is a clear, colourless liquid which has a faint, mild odour and the formula C10H20O4. It is slightly soluble in water and is miscible with organic solvents.
BDGA is produced by reacting ethylene oxide with anhydrous n-butyl alcohol to form diethylene glycol butyl ether. The ether is then reacted with acetic acid to form butyl diglycol acetate.
Storage and distribution
Butyl di glycol acetate is transported in steel drums. It is not classified as dangerous for any form of transport. It has a flash point of 124° C (closed cup) and a specific gravity of 0.98.
The main application for BDGA is as a solvent in formulations for paints, cleaning fluids, coatings and inks. In the coatings industry it is utilized as latex coalescent for water-based industrial coatings. In the paint industry, it is a high boiling solvent and leveling agent, and a coalescent in paints and lacquers. It is an effective solvent for cleaning fluids and is now marketed as a cleaning agent in the electronics industry. In the ink industry it is valued as a solvent for specialty printing inks and for ball point pen pastes. It is also a suitable solvent for dyes used in wood stains and furniture polishes.
