Sikaflex 552 AT
- Elastic STP adhesive
- 1-component adhesive
- For bonding large sections
Sikaflex 552 AT is a 1-component elastic assembly adhesive based on the Sika Silane Terminated Polymer (STP) technology. This adhesive is specifically designed for bonding large components in vehicle assembly. It is suitable for bonding coated metal, GRP, ceramic materials and plastics. It bonds well to a wide range of substrates with minimal pre-treatment. Sikaflex 552 AT is produced in accordance with the ISO 9001/14001 quality management systems and within the framework of the "responsible care" programme.
Benefits of Sikaflex 552 AT
- Resistant to ageing and weathering.
- Good adhesion to a wide variety of substrates without the need of a primer.
- Isocyanate- and solvent-free.
- Capable of withstanding high dynamic stresses.
- High elasticity and low VOC content.
- Can be painted.
- Silicone and PVC-free.
Applications
Sikaflex 552 AT is suitable for joints that will be subjected to dynamic stresses. Suitable substrate materials are metals, particularly aluminium, metal primers, paint coatings, sheet steel, ceramic materials and plastics. It bonds well to a wide range of substrates with minimal pre-treatment. Consult technical 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 must be performed to ensure adhesion and material compatibility.
