Latent curing agents for epoxy resins |
| 摘要 |
Hydrazides of the formula (I) or (II) N-CH2CH2CONHNH2)3 (I) (NH2NHCOCH2CH2)2N-R-N-CH2CH2CONHNH2)2 (II) are good latent curing agents for epoxy resin, in the formula (II) R is divalent hydrocarbon residue having 2-24 carbon atoms. The curing agents are useful in formulating novel storable one-package, heat-curable epoxy resin-based compositions.
