    FAQ - Technical & Supply Chain

    • Q:

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

      A: 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.
    • Q:

      What is Adipic Acid Dihydrazide used for?

      A: 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.
    • Q:

      Which batch specifications should be agreed for Adipic Acid Dihydrazide?

      A: 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.
    • Q:

      How should ADH be packed and approved for delivery?

      A: 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.
    • Q:

      What are the typical physical properties of Adipic Acid Dihydrazide?

      A: 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.
