Are ADH and Diacetone Acrylamide (DAAM) interchangeable in a waterborne crosslinking system?

No. Adipic Acid Dihydrazide, CAS 1071-93-8, is the difunctional hydrazide crosslinker; DAAM is the carbonyl-functional vinyl monomer incorporated into the polymer. The two are complementary rather than interchangeable. State the polymer carbonyl content and the desired ADH stoichiometry.

What is Adipic Acid Dihydrazide used for?

ADH is used as a post-polymerization crosslinker for carbonyl-functional acrylic, styrene-acrylic and vinyl-acetate emulsions. It can also be used in coatings, inks and adhesives, and as a hydrazide building block where a difunctional amine-like reagent is required.

Which batch specifications should be agreed for Adipic Acid Dihydrazide?

Agree purity and method, appearance, melting range, loss on drying, iron, chloride, sulfate and any particle-size or dissolution requirement. Published commercial grades use different purity and impurity limits, so put the test methods and acceptance limits in the quotation and purchase order.

How should ADH be packed and approved for delivery?

Confirm a sealed polyethylene-lined carton or equivalent moisture-resistant package, net weight, manufacturing date, storage conditions, sampling and dissolution test where required. ADH is normally supplied as a crystalline powder and should be protected from moisture and incompatible oxidizing or strongly acidic materials.

What are the typical physical properties of Adipic Acid Dihydrazide?

ADH is usually a white to slightly yellow crystalline powder with melting range around 178-185 C and good solubility in water and polar solvents. Compare the offered lot data against the agreed specification, including particle size and dissolution for your application.

Adipic Acid Dihydrazide (ADH) CAS 1071-93-8
