Adipic Dihydrazide (ADH), known chemically as hexanedihydrazide (CAS: 1071-93-8), is a pivotal component in the formulation of high-performance epoxy coatings. For industrial procurement managers and product development scientists, understanding ADH's role and how to source it effectively is key to achieving superior results. This guide focuses on ADH as a curative for epoxy resins, highlighting its advantages and the benefits of sourcing from China.

ADH is a white crystalline powder, valued for its purity and consistent chemical properties. As an epoxy resin curative, it offers distinct advantages over traditional curing agents. Its reactivity profile allows it to function as a latent curing agent, providing extended pot life at ambient temperatures, which is crucial for processing complex coatings, particularly in powder coating applications. When heat is applied, ADH effectively crosslinks the epoxy resin, forming a dense, three-dimensional network.

The benefits of using ADH in epoxy formulations are significant. Materials cured with ADH exhibit excellent color stability, outstanding weathering resistance, superior adhesion to various substrates, and enhanced toughness and durability. These properties make ADH-cured epoxy coatings ideal for demanding applications in automotive, aerospace, construction, and industrial maintenance sectors. For example, in powder coatings, ADH contributes to smooth finishes and robust protection against corrosion and abrasion.

For businesses looking to buy Adipic Dihydrazide for their epoxy coating needs, China presents a robust market with numerous reputable manufacturers and suppliers. Sourcing ADH from China offers the dual advantage of competitive pricing and consistent availability, especially for bulk purchases. Procurement managers can leverage this by engaging directly with manufacturers to secure favorable terms and ensure a steady supply chain.

When selecting an ADH supplier, buyers should prioritize those who provide comprehensive technical data, including specifications on purity, melting point, and solubility, alongside safety data sheets. Reliability, quality assurance, and responsive customer service are paramount. Partnering with a trusted China manufacturer ensures that the ADH meets the required industrial standards, thereby guaranteeing the performance and integrity of the final epoxy coating product.

In conclusion, Adipic Dihydrazide is an indispensable chemical for advanced epoxy coating formulations. Its unique curing properties enhance product durability, aesthetics, and protective capabilities. By strategically sourcing ADH from qualified Chinese manufacturers, companies can achieve both performance excellence and cost-effectiveness in their coating applications.


For procurement professionals seeking to enhance their epoxy coating formulations, Adipic Dihydrazide (ADH) from China offers an optimal blend of performance benefits and economic advantages. Engaging with trusted manufacturers ensures access to high-quality materials and competitive pricing, driving innovation and product excellence.
