Adipic dihydrazide

Adipic dihydrazide (CAS 1071-93-8 ), commonly abbreviated as ADH, is a bifunctional hydrazide used as a crosslinker and curing agent across coatings, adhesives, and polymer systems. It reacts with carbonyl-functional resins at ambient or low temperatures, enabling formulations to cure without elevated heat. In waterborne coatings, ADH crosslinks ketone-functional acrylic dispersions. This process improves hardness, water resistance, and film durability in architectural and industrial finishes. Adhesive and sealant formulators use it to build cohesive strength in emulsion-based systems. It is particularly effective where thermal curing is impractical. In polymer chemistry, ADH acts as a chain extender and building block for polyurethanes, polyamides, and hydrogel networks. These applications require controlled crosslink density for optimal performance. Personal care applications include its use as a stabilizer in formulations where carbonyl-reactive chemistry helps protect ingredients. This specific chemistry helps protect active ingredients from degradation over time. Adipic dihydrazide is supplied as a white crystalline powder available in technical and high-purity grades. Specifications are typically defined by assay content, moisture levels, and melting point range. Packaging ranges from kilogram-scale bags to bulk quantities suitable for industrial procurement.
