Description

Diacetone alcohol ( CAS 123-42-2 ), commonly abbreviated as DAA, is a slow-evaporating ketone-alcohol solvent used across coatings, adhesives, and industrial cleaning applications. Its dual functional group chemistry makes it compatible with a broad range of resins, enabling effective solvation where faster solvents fall short in complex formulations. In coatings and lacquers, DAA dissolves nitrocellulose, epoxy, and acrylic resins, supporting formulations that require extended open time and leveling performance for high-quality finishes. Adhesive and sealant manufacturers use it as a reactive diluent and crosslinking co-solvent, particularly in systems where controlled cure rate is a production requirement for stability. In personal care, DAA functions as a carrier solvent in nail care formulations and surface-active cosmetic products. Polymer processors also use it as a coupling agent and stabilizer. This additive helps to improve resin homogeneity during compounding. DAA is supplied as a clear liquid in drum, IBC, and bulk tanker quantities for industrial scale operations. Technical grade is the standard commercial specification, with high-purity grades available for cosmetic and specialty coating applications requiring strict adherence to quality. Buyers should confirm water content and purity thresholds, as residual moisture affects performance in moisture-sensitive resin systems and overall chemical stability.
