Abstract

See full text

An enhanced anaerobic adhesive composition containing microencapsulated metal ions is disclosed. Microencapsulated metal ions, such as iron oxide, copper naphthenate, cobalt naphthenate, ferrocene, and ferrocene derivatives, act as bonding sites in the composition, such that the composition achieves more complete polymerizations in a shorter curing time. The curing properties and the cure quality are significantly improved by the inclusion of microencapsulated metal ions. The composition can be used to bond metal and plastic substrates.
