Sikaflex®-522 adheres well to a wide variety of substrates and is suitable for interior and exterior elastic sealing and bonding applications. It is suitable for applications in areas of air ventilation and incidental food contact. Suitable substrate materials include timber, glass, metals, metal primers and paint coatings (2-part systems), ceramic materials and plastics.
Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-522 on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.
