Diacetone Acrylamide (DAAM), CAS 2873-97-4, is also known as N-(1,1-dimethyl-3-oxobutyl)acrylamide. It is a ketone-functional vinyl monomer used in waterborne emulsion-polymer crosslinking systems, typically with adipic acid dihydrazide (ADH). Confirm the intended resin or crosslinking system, required specification, quantity, packaging, destination and document availability before ordering.

FAQ - Technical & Supply Chain
-
Q:
What is the difference between Diacetone Acrylamide (DAAM) and ADH?
A: DAAM, CAS 2873-97-4, is the ketone-functional vinyl monomer incorporated into an emulsion polymer. Adipic Acid Dihydrazide (ADH) is the hydrazide crosslinker added to react with those carbonyl groups after film formation. They are not substitutes, and the full crosslinking system should be specified together. -
Q:
What is Diacetone Acrylamide used for?
A: DAAM is used in waterborne acrylic, styrene-acrylic and vinyl-acetate emulsions to introduce ketone-carbonyl functionality for post-polymerization ADH crosslinking. Typical end uses include paints, wood coatings, adhesives, paper coatings and textile or leather finishes. -
Q:
Which release specifications should be compared for DAAM?
A: Compare DAAM purity and method, appearance, water, residual acrylamide, total inhibitor, melting behavior and any color limit. Published grades range from light-yellow flake to high-purity white flake and use different acrylamide and inhibitor controls. -
Q:
What should be confirmed before approving DAAM for a waterborne resin system?
A: Provide the comonomer package, target DAAM level, emulsion solids, pH, polymerization route and intended ADH addition stage. Confirm a sealed polyethylene-lined carton, net weight, storage temperature and inhibitor basis before approving application trials.
