Sikaflex®-522 shows good adhesion to a wide range of substrates and is suitable for elastic sealing and bonding applications both indoors and outdoors. This product is suitable for applications in the air conditioning and ventilation sector, as well as in food processing plants.
Suitable substrates are wood, glass, metals, metal primers and paints (two-component systems), ceramic materials and plastics. Observe the manufacturer's recommendations before using Sikaflex®-522 on materials at risk of stress cracking. Preliminary tests must be carried out with original materials to avoid stress cracking. This product is only suitable for experienced users. To ensure adhesion and material compatibility, preliminary tests must be carried out with original materials under the respective conditions.

The bonding surfaces must be clean, dry and free of grease, oil and dust. The surface pretreatment depends on the specific nature of the substrate and is crucial for a permanent bond. Information on substrate pretreatment can be found in the current Sika® pretreatment table. We recommend cleaning the surface to be bonded beforehand (e.g. with spirit) to remove any dirt and grease residue.
