PolyOlefin Bonding

A process for bonding a polyolefin, polyfluoroolefin, polyethylene terephthalate, polyacetal, nylon or plasticizer-rich soft polyvinyl chloride substrate to a like substrate or for bonding a polyolefin, polyfluoroolefin, polyethylene terephthalate, polyacetal, nylon or plasticizer-rich soft polyvinyl chloride substrates to another substrate which comprises applying to the surface of at least one of the substrates to be bonded together an adhesion promoter composition comprising 0.001-10 wt.

A primer comprising an organometallic compound and an organic polymer, which is useful in bonding non-polar or highly crystalline resin substrates together or bonding said resin substrates and another material, such as a solid material, a coating material, paint or printing ink by using a 2-cyanoacrylate.
