What is Diacetone alcohol?
Diacetone alcohol (CAS 123-42-2), commonly abbreviated as DAA, is a slow-evaporating ketone-alcohol solvent.
Where is Diacetone alcohol used?
- Coatings and lacquers: dissolves nitrocellulose, epoxy, and acrylic resins, supporting extended open time and leveling
- Adhesives and sealants: reactive diluent and crosslinking co-solvent for controlled cure rate
- Personal care: carrier solvent in nail care and surface-active cosmetic products
- Polymer processing: coupling agent and stabilizer that improves resin homogeneity during compounding.
Good to know: Buyers should confirm water content and purity thresholds, as residual moisture affects performance in moisture-sensitive resin systems and overall chemical stability.
Commercial specifications
- Technical grade standard; high-purity grades for cosmetic and specialty coating applications
- Clear liquid in drum, IBC, and bulk tanker quantities
