Diacetone Acrylamide
CAS Number: 2873-97-4
Diacetone acrylamide (DAAM) is a ketone-functional acrylic monomer that enables self-crosslinking of emulsion polymers when used with adipic acid dihydrazide (ADH) as the crosslinking agent. The ketone carbonyl reacts with hydrazide groups at room temperature to form hydrazone crosslinks, creating crosslinked latex films without thermal activation — ideal for ambient-cure waterborne coatings.
