          Pure product is white crystal, soluble in water, poisoning. Mainly used in epoxy powder coating curing agent and coating additives, metal deactivators and other polymer additives and water treatment agent. Just like bifunctional cross-linking reagent, it is designed to work with aldehydes to generate relatively stable hydrazone linkages. It can be used as a protein drug carrier after cross-linking with sodium hyaluronate. Playing  Cross-linking role in the cross-linking of Acrylamide, N-(1,1-dimethyl-3-oxobutyl) aqueous emulsions and water-soluble polymers. Can also be used as indoor formaldehyde adsorbent and intermediate raw material.

          Uses: Adipic acid dihydrazide (ADH) is a high melting point powdered compound produced by reacting an organic acid with a hydrazine. It can be used as a latent curing agent for epoxy resins (EP). EP/SPH is used for adhesion. The coating system of the powder coating obtained from the material system has excellent flexibility, water resistance, weather resistance, corrosion resistance, insulation and decorative properties. At home and abroad today, in particular, it is an indispensable latent curing agent for the manufacture of high-quality, high-temperature, fast-solid, anti-corrosion powders and petroleum pipelines, aerospace, and aviation oil. And in the epoxy powder, glass steel products, such as increasing the intensity of the ideal. In combination with Acrylamide, N-(1,1-dimethyl-3-oxobutyl) (DAAM), high performance water-soluble coatings can be made.
