Pattex Super Glue for Glass is a cyanoacrylate adhesive. Bonding surfaces must be clean, grease-free, and dry (clean with white spirit or acetone if necessary) and fit precisely. Apply the adhesive thinly on one side. The thinner the adhesive film, the faster and stronger the bond. Press the parts together immediately and fix for about 15-60 seconds, depending on the material (possibly using a clamp).
