Mainly used for epoxy powder coating curing agent and coating auxiliaries, metal deactivator and other polymer auxiliaries and water treatment agents.

Adipic acid dihydrazide bifunctional compound can be used as protein drug carrier after cross-linking with sodium hyaluronate. With diacetone acrylamide, it plays a cross-linking role in the post-crosslinking of water emulsions and water-soluble polymers, such as water-based coatings, adhesives, fibers, plastic film treatment, hair spray, etc. It can also be used as epoxy powder coating curing agent and Water-based paint additives, metal deactivators and other polymer additives and water treatment agents, indoor formaldehyde adsorbents and intermediate raw materials.

Homobifunctional cross-linking reagents, specific for aldehydes, generate relatively stable hydrazone linkages. Especially for linking glycoproteins such as antibodies.
