Sikaflex®-522 shows good adhesion to a variety of substrates and is suitable for elastic sealing and bonding applications indoors and outdoors. This product is suitable for applications in the HVAC sector, as well as for 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 prone to stress cracking. Preliminary tests must be carried out with original materials to avoid stress cracks. 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 from grease, oil and dust. Surface pretreatment depends on the specific nature of the substrate and is crucial for a durable bond. Information on substrate pretreatment can be found in the current Sika® pretreatment table. We recommend cleaning the surface to be bonded beforehand to remove dirt and grease residues.
