Sikaflex®-552 AT is suitable for joints that will be subjected to dynamic stresses. Suitable substrate materials are metals, particularly aluminum, metal primers, paint coatings, sheet steel, ceramic materials and plastics. It bonds well to a wide range of substrates with minimal pre-treatment.. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-552 AT on materials prone to stress cracking. Sikaflex®-552 AT is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.
