The present invention describes the use in epoxy resin compositions of semicarbazones of the general formula (I) having the meanings stated for the residues R
1
, R
2
, R
3
and R
4
.
These semicarbazones exhibit elevated latency in epoxy resin compositions and are thus outstandingly suitable as latent curing accelerators for single-component epoxy resin compositions.
本发明描述了在环氧
树脂组合物中使用具有通式(I)中所述残基R1、R2、R3和R4的半卡巴
肼的用途。这些半卡巴
肼在环氧
树脂组合物中表现出卓越的潜伏期,因此非常适合作为单组分环氧
树脂组合物的潜伏固化
促进剂。
