Sikaflex®-554 is suitable for joints that are exposed to dynamic loads. Suitable substrates are metals, especially aluminum, metal primers, paints, sheet steel, ceramic materials and plastics. Sikaflex®-554 shows good adhesion to a variety of substrates with minimal pre-treatment. Follow the manufacturer's recommendations before using Sikaflex®-554 on materials at risk of 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.

Adhesion surfaces must be clean, dry and free from grease, oil, dust and contamination. The surface pre-treatment depends on the specific nature of the substrate and is crucial for a durable bond. Instructions for substrate pre-treatment can be found in the current Sika® pre-treatment table. The information contained therein is based on experience and must always be verified by preliminary tests with original materials.
