An adhesive that permanently adheres difficult-to-bond polymers to themselves and other materials has been introduced by XlynX Materials. The BondLynx adhesive creates covalent chemical bonds between polymer chains via bis-diazirine chemistry, permanently cross linking them together through strong carbon-carbon bonds.

Conventional adhesives typically take advantage of mechanical forces to hold materials together. The covalent bonds formed by BondLynx resemble the structure of carbon atoms in strong carbon-carbon bonds, said XlynX Materials in its announcement. Once BondLynx has been applied to a polymer, the cross-linking process can be initiated via heat, ultraviolet or visible light, or an electric field, depending on the specific demands of the manufacturing process.
