Di Acetone Alcohol (DAA)
Diacetone alcohol or DAA is an oxygenated solvent derived from acetone which has two alcohol and ketone functions. It has a high purity. It is colorless and odorless and has a low evaporation rate.
Diacetone alcohol is mainly used in paints and coatings (coil coatings, wood varnishes, architectural coatings…). It is a good solvent for organic peroxides and can also be used for the treatment of textiles and leather, in chemical synthesis, or as a cleaning solvent.
