Adipic Acid Dihydrazide (ADH)
TECHNICAL SPECIFICATIONS
Adipic Acid Dihydrazide (ADH) is a high-efficiency Crystalline Grade cross-linking agent specifically designed for water-based acrylic emulsions. Boasting 99% min purity, ADH serves as the essential curing partner for carbonyl-functional monomers like DAAM.
This white crystalline powder enables the development of “one-pack” self-crosslinking systems that cure at ambient temperatures upon evaporation of water. It is highly valued for producing coatings with superior weatherability and chemical resistance.
Beyond coatings, ADH acts as a powerful formaldehyde scavenger in resin applications and as a hardener for specialized epoxy systems. Its low toxicity and high reactivity make it a preferred choice for sustainable industrial formulations.
APPLICATIONS
- Coating Crosslinker: Combined with DAAM for high-performance, room-temperature curing architectural paints.
- Resin Hardener: Used as a latent curing agent in epoxy powder coatings and high-solids adhesives.
- Chemical Intermediate: Employed in the synthesis of pharmaceuticals and specialized photographic chemicals.
SAFETY & RISKS
Non-hazardous for transport but may cause mild respiratory irritation. Use Dust Masks, Safety Goggles, and Standard Protective Gloves during use.
PACKAGING
25 kg fiber drums or cardboard boxes with internal plastic bags.
