- Strong adhesion to a wide variety of substrates without the need for a primer.
- Isocyanate- and solvent-free.
- Capable of withstanding high dynamic stresses.
- High elasticity and low VOC content.
- Paintable.
- Silicone- and PVC-free.
Applications
Sikaflex 552 AT is suitable for bonded joints subjected to dynamic stresses. Compatible substrate materials include metals (particularly aluminium), primed metals, paint coatings, sheet steel, ceramic materials and plastics. The adhesive provides excellent adhesion to a wide range of substrates with minimal pre-treatment. Seek technical advice and perform tests on actual substrates before using Sikaflex 552 AT on materials prone to stress cracking. This product is intended for professional use only. Testing under real application conditions is essential to ensure proper adhesion and material compatibility.
