Anaerobic sealant unaffected by water contamination.

摘要

An anaerobic sealant material comprises an acrylate or methacrylate monomer, a hydroperoxide or perester initiator, an accelerator having -SO2NHCO-functionality, and a transition metal co-accelerator gives substantially reduced moisture sensitivity if the transition metal co-accelerator is a combination of a copper salt or complex at the level of 0.5-10ppm copper and an iron complex or salt at the level of 0.5-60ppm iron.
