Application
Sikaflex®-252 is suitable for assemblies that are exposed to dynamic loads. Suitable substrates are wood, metals, especially aluminium (also anodised), sheet steel (also phosphated, chromated or galvanised), metal primers and paints (two-component systems), ceramic materials and plastics. Follow the manufacturer's recommendations before using Sikaflex®-252 on materials susceptible to stress cracking. Preliminary tests must be carried out with original materials to avoid stress cracking. 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.
