Abstract: An adhesive composition is described comprising unpolymerized cyclic olefin, a ring opening metathesis polymerization (ROMP) catalyst or precatalyst thereof, and one or more adhesion promoter polymers. In one embodiment, the adhesion promoter is a polyolefin comprising maleic anhydride or silicon-containing moieties. In one embodiment, a combination of at least one polymeric polyisocyanate and at least one polyolefin comprising maleic anhydride or silicon-containing moieties provides a synergistic improvement. In another embodiment, a polymeric polyisocyanate adhesion promoter comprising oxygen atoms in the backbone has been found useful for bonding substrates such as polyamide, polyether ether ketone, or polyether imide. Also described are methods of bonding a substrate and articles, such as an electric battery cold plate assembly.

Abstract: Provided is an aqueous primer composition including a first thermosetting resin that is a particulate solid at ambient conditions and a second thermosetting resin that is liquid at ambient conditions and acting as a reactive coalescent agent in which the first thermosetting resin is at least partially soluble. The second thermosetting resin acts as a coalescent agent to enable a continuous primer film to be formed as the primer is being dried before it is cured. The composition further includes a curative that is substantially water-insoluble and reactive with the first and second thermosetting resins. The overall composition can contain up to 4 percent by weight of volatile solvents, other than water and provides a shelf-stable primer that can form a continuous film without the need for added organic solvents.
