Sikaflex®-552 is a high performance elastic gap-filling 1-c structural assembly adhesive that cures on exposure to atmospheric humidity to form a durable elastomer. Sikaflex®-552 contains no isocyanate. Sikaflex®-552 is manufactured in accordance with ISO 9001/14001 quality assurance system and with the responsible care program.
Areas of Application:
Sikaflex®-552 is suitable for structural joints that will be subjected to dynamic stresses. Suitable substrate materials are metals, particularly aluminium (including anodized components), sheet steel (including phosphated, chromated and zinc-plated components), ceramic materials and plastics. Seek manufacturer's advice before using on plastics that are prone to stress cracking. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
