Adipic acid dihydrazide is also known as Jidihydrazide. The pure product is white crystal, easily soluble in water and poisonous. It is mainly used as epoxy powder coating curing agent and coating additive, metal deactivator and other polymer additives and water treatment agent. The same bifunctional cross-linking reagent, specially used for aldehydes, generates relatively stable hydrazone links. It can be used as a protein drug carrier after cross-linking with sodium hyaluronate. And diacetone acrylamide play a cross-linking role in the cross-linking of water emulsion and water-soluble polymer. It can also be used as indoor formaldehyde adsorbent and intermediate raw material.

Uses: Adipic acid dihydrazide (ADH) is a high-melting powder compound, which is prepared by the reaction of organic acid and hydrazine. It can be used as a latent curing agent for epoxy resin (EP). EP/SPH is used as the adhesive The coating film of the powder coating prepared by the material system has very excellent flexibility, water resistance, weather resistance, corrosion resistance, insulation and decoration. It is an indispensable latent curing agent in the fields of high-temperature fast-solidifying heavy-duty anti-corrosion powder and petroleum pipelines, aerospace, and aviation fuel at home and abroad. And the effect is very ideal in terms of increasing the strength of epoxy powder and glass fiber reinforced plastic products. Especially in combination with diacetone acrylamide (DAAM), it can be made into high-performance water-soluble coatings.
