Technicure® IDH, Isophthalic Dihydrazide, a benzyl backboned dihydrazide, is commonly used with epoxy resins in single component systems where cure above 160C, and high Tg's as well as acid resistance are required. When a faster cure is needed, IDH can also be accelerated resulting in a "snap cure" system. Some suggested accelerators for IDH include Technicure LC- 80, and any of the substituted ureas, including Technicure MDU-11, Technicure PDU-17 or Technicure TDU-20. IDH can also be used as a curative for acrylics and urethanes, by Michael Addition, dramatically increasing crosslink density. IDH is also approved by the FDA for indirect food contact under 21 CFR Chapter 175.300.

ADVANTAGES

• Long Pot Life with epoxy resins
