Adipic Acid Dihydrazide (ADH) (CAS 1071-93-8) is a crystalline crosslinking agent that appears as a white to slightly yellow powder at 99% minimum purity, used as the curing partner for carbonyl-functional monomers such as DAAM in water-based acrylic emulsions and as a formaldehyde scavenger in resin systems. This white crystalline powder enables the development of "one-pack" self-crosslinking systems that cure at ambient temperatures upon evaporation of water. It is highly valued for producing coatings with superior weatherability and chemical resistance. Beyond coatings, ADH acts as a powerful formaldehyde scavenger in resin applications and as a hardener for specialized epoxy systems. Its low toxicity and high reactivity make it a preferred choice for sustainable industrial formulations.
