Technicure® ADH, Adipic Dihydrazide, a C-4 backboned dihydrazide, is commonly used with epoxy resins in single component systems where cure above 120C, good adhesion to oily metal and good toughness are required. When a faster cure is needed, ADH can also be accelerated resulting in a "snap cure" system. Some suggested accelerators for ADH include Technicure LC-80, and any of the substituted ureas, including Technicure MDU-11, Technicure PDU-17 or Technicure TDU-20. These accelerators will decrease the activation temperature of ADH, without compromising, and perhaps enhancing performance properties. ADH can also be used as a curative for acrylics and urethanes, by Michael Addition, especially with its water solubility, >50%, ADH can be used as a water-phase crosslinker in water dispersed urethanes and acrylics, not to mention as part of the polymer backbone.
