摘要：
A curing composition is useful for a multi-component epoxy resin compound and includes at least one first polyamine, at least one second polyamine, and at least one polyphenol from the group of bisphenols and novolac resins as an accelerator. Upon contact with atmospheric oxygen, the curing composition discolors within a few days and therefore leakages can be visually identified.
