Diacetone Acrylamide (DAAM) Self-Crosslinking Agent
CAS Number: 2873-97-4
Diacetone Acrylamide (DAAM) is a ketone-functional acrylamide monomer supplied at ≥99% purity that enables ambient-temperature self-crosslinking in acrylic emulsions when used in conjunction with adipic acid dihydrazide (ADH). The carbonyl groups in the DAAM-containing latex react with ADH hydrazide groups during film drying and coalescence, forming a hydrazone crosslink network without external heat input. Loading of 2–5% DAAM with stoichiometric ADH delivers excellent solvent resistance, water resistance, and blocking resistance.
