ABSTRACT:
A curable composition, having utility for threadlocking engageable members of a threaded mechanical fastener, comprising: a reactive silicone (meth)acrylate emulsified in an aqueous medium, optionally further comprising a polymerizable non-silicone (meth)acrylate monomer or oligomer; and a microencapsulated peroxy initiator which is initiatingly effective for cure of the reactive silicone (meth)acrylate. The curable composition may be usefully employed for adhesively bonding engageable structural parts, by applying the aqueous emulsion of the reactive silicone (meth)acrylate, containing a microencapsulated peroxy initiator, to at least a portion of an engagement surface of a matable part which is matably engageable with a complimentary engagement structure, to yield an emulsion-coated engagement surface, drying the emulsion-coated engagement surface to form a dried coating thereon; and thereafter engaging the surface having the dried coating thereon, with the complimentary engagement structure, to release the microencapsulated peroxy initiator and bond the matable part and complimentary engagement structure.
