Patent ID: 7973119

Claim:
A two part adhesive system comprising: A. a first part comprising an imine within structure wherein K is wherein R 1 -R 2 are each independently selected from the group consisting of hydrogen, alkenyl, and alkynyl; and A-B are each independently selected from the group consisting of linear, branched, or cyclic alkyl or alkenyl which may be interrupted with heteroatoms or substituted by functional groups, or A and B taken together form a cyclic or polycyclic alkyl or alkenyl structure, which may be interrupted with heteroatoms or substituted by functional groups; E is selected from the group consisting of a linear, branched and cyclic hydrocarbon with or without one or more nitrogen-containing substituents thereon, a heterocyclic, an aromatic or an organosiloxane group or part thereof or linkage; and R 3 is selected from the group consisting of a hydrocarbon, a heterocyclic, an aromatic and an organosiloxane group or linkage; w is 1-100; y is 1-100 and z is 0-100, wherein when more than one of K, E or R 3 are present, each instance thereof is defined independently from the other instance(s); and B. a second part comprising a compound containing at least one methylene linkage having at least one electron withdrawing substituent attached thereto, wherein the electron withdrawing substituent is selected from the group consisting of nitrile, carboxylic acids, carboxylic esters, sulphonic acids, ketones and nitro.
