Areas of Application

Sikaflex®-552 is suitable for 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 and perform tests on original substrates before using Sikaflex®552 on materials prone to stress cracking. Sikaflex®-552 is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.
