Technical Data Sheet for Adipic Acid Dihydrazide（TDS）

Adipic acid dihydrazide, also known as adipic dihydrazide , pure white crystal,

 soluble in water, poisoning. Mainly used in epoxy powder coating curing agent and

 coating additives, metal deactivator and other polymer additives and water

 treatment agents. Isobifunctional cross-linking reagent, dedicated to aldehydes, to

 produce relatively stable hydrazone links. It can be cross-linked with sodium

 hyaluronate as a protein drug carrier. It is crosslinked with diacetone acrylamide in

 the crosslinking of water emulsion and water-soluble polymer. It can also be used

 as indoor formaldehyde adsorbent and intermediate raw materials.
