Photo-adhesive material was prepared for adhesion between dissimilar materials, with a radical photo-initiator and a methacryl monomer having 2-chloropyridyl group. The methacryl monomer was obtained as a stable colorless liquid. Photo-adhesion was then performed between a glass substrate and another one (glass or dissimilar materials), with 1 J/cm2 of UV irradiation at a wavelength of 365 nm. Shear stress up to 6.2 MPa was recorded, and thermal dismantlement of the sample was also observed. Furthermore, using residue of the adhesive layer on each substrate, re-adhesion was performed with gentle heating.
