Adipic Dihydrazide (ADH), identified by its CAS number 1071-93-8, is a highly effective crosslinking agent for water-based emulsions, playing a crucial role in enhancing the performance of paints, adhesives, and other polymer-based products. For formulation scientists and procurement specialists, understanding the properties and applications of ADH, and knowing how to source it from China, is vital for product development and manufacturing efficiency.

ADH is a white crystalline powder known for its symmetrical structure and the presence of reactive hydrazide groups at each end. This molecular design makes it exceptionally well-suited for crosslinking reactions, particularly with polymers containing carbonyl functionalities, such as those modified with diacetone acrylamide (DAAM) or acetoacetoxyethyl methacrylate (AAEM). In these systems, ADH reacts to form stable hydrazone linkages, creating a crosslinked polymer network that significantly improves the final product’s properties.

The primary benefits of using Adipic Dihydrazide in water-based emulsions are manifold. It contributes to enhanced film hardness, improved scrub and stain resistance, better adhesion to various substrates, and increased overall durability. For paints and coatings, this translates into longer-lasting finishes that can withstand environmental stresses. In adhesives, ADH enhances bond strength and moisture resistance. The ability to achieve these performance improvements at ambient temperatures further adds to its appeal for formulators.

For companies looking to buy Adipic Dihydrazide, China offers a compelling sourcing option. Chinese manufacturers are a key global source for high-purity ADH, often at competitive prices due to economies of scale. Procurement managers can find reliable suppliers who adhere to strict quality control standards, ensuring that the purchased ADH meets the exacting requirements for water-based emulsion applications.

When selecting a supplier, it is important to verify their manufacturing capabilities, quality certifications, and their ability to provide consistent product. Direct engagement with China-based manufacturers allows for better understanding of product specifications, availability, and pricing. For those investigating how to buy ADH, prioritizing suppliers with a proven track record in producing fine chemicals for industrial use is recommended.

In essence, Adipic Dihydrazide is an indispensable crosslinking agent for water-based emulsions, offering significant performance enhancements. Sourcing ADH from reputable Chinese manufacturers provides a strategic advantage, ensuring quality, cost-effectiveness, and a reliable supply chain for companies aiming to innovate in the paints, adhesives, and coatings industries.


Securing Adipic Dihydrazide from reliable China manufacturers empowers businesses to achieve superior performance in water-based emulsion products. The combination of ADH's crosslinking efficacy, supported by competitive pricing and quality assurance from Chinese suppliers, makes it an essential raw material for product innovation.
