Adipic dihydrazide

Adipic dihydrazide (CAS 1071-93-8), commonly abbreviated as ADH, is a bifunctional hydrazide used as a crosslinker and curing agent in coatings, adhesives and polymer systems.

Where is Adipic dihydrazide used?

• Waterborne coatings: crosslinks ketone-functional acrylic dispersions, improving hardness, water resistance and film durability in architectural and industrial finishes
• Adhesives and sealants: builds cohesive strength in emulsion-based systems where thermal curing is impractical
• Polymer chemistry: chain extender and building block for polyurethanes, polyamides and hydrogel networks
• Personal care: stabilizer that protects active ingredients from degradation
• It reacts with carbonyl-functional resins at ambient or low temperatures, enabling cure without elevated heat.

Good to know: These applications require controlled crosslink density for optimal performance.

Commercial specifications

• Technical and high-purity grades
• Specifications typically defined by assay content, moisture levels and melting point range
• Packaging from kilogram-scale bags to bulk quantities
