New 'molecular glue' permanently bonds any plastic to plastic

September 20, 2021

XlynX Materials has created a new class of adhesives they are calling “molecular glues”. These make it possible to permanently adhere difficult-to-bond polymers such as polyethylene and polypropylene to themselves, and to other materials, through exceptionally strong chemical bonds.

Conventional adhesives typically take advantage of mechanical forces to hold materials together. BondLynx employs bis-diazirine chemistry to create covalent chemical bonds between polymer chains, permanently crosslinking them together through strong carbon–carbon bonds.
