Due to the evaporation coldness, the surfaces of the glass elements are slightly cooled down after cleaning. Therefore, before fixing the two glass elements and applying the UV adhesive briefly heat the cleaned surfaces to 20-30 Kelvin above room temperature using a hot air device. In order to position two glass elements exactly and to fix them during the bonding process, you need suitable fixing aids. These are important to secure the individual parts to be bonded against vibrations or slipping. This is because the UV adhesive polymerises during the curing process and forms a network. Inadequate fixing of the bonded parts can, in case of doubt, lead to this network being damaged, and that in turn leads to a loss of strength. Important: You can only achieve the desired professional end result by using high-quality fixing aids.

One of the last steps is to cure the adhesive with a suitable UV light. Always select your UV lamps according to the area size of the bond, to achieve an even and simultaneous exposure of the entire bonding surface. This ensures that the adhesive cures evenly and prevents unintentional uneven stresses from building up in the bond, which can cause the bond to fail. Hand lamps are particularly suitable for bonding metal parts or short adhesive edges. For longer edges, tubular lamps or elongated UV lamps in the appropriate size are the right choice. The Twin-LED is a practical and mobile solution for curing smaller surfaces. You will find UVA lamp systems for curing UV adhesives in all variants in our range. Of course, they are all equipped with special filter screens to prevent damage to skin and eyes.
