Other Names

• DAAM

• DAA

• Diacetonyl Acrylamide

• N-(1,1-Dimethyl-3-oxobutyl)acrylamide

Production

DAAM is synthesized through the reaction of acrylamide derivatives with ketone carbonyl groups. It is commonly produced through polymerization, often stabilized using MEHQ inhibitors.

Why It Is Preferred

• High cross-linking capacity

• Chemical stability and heat resistance

• Good solubility in water-based systems

• Enhances durability in coatings and adhesives

Alternative Products

• N,N'-Methylenebisacrylamide (MBAA): Used in polymer cross-linking.

• Polyvinyl Acetate (PVA): Alternative for adhesives and coatings.

• Epoxy Resins: Preferred in high mechanical strength applications.
