SIKAFLEX 552 AT BLACK - CARTRIDGE 300 ML
Sikaflex 552 AT is a high-performance elastic gap-filling PUR-Hybrid adhesive based on the Sika Silane Terminated Polymer (STP) technology.
Characteristics
- 1-C silane-terminated polymer based technology
- Ageing and weathering resistant
- Bonds well to a wide variety of substrates with practically no need for priming
- Capable of withstanding high dynamic stresses
- Can be over-painted
- Low odour
- Non-corrosive
- High electrical resistance
- Low VOC content and solvent-free
- Silicone- and PVC-free
Application
- Suitable for structural joints that will be subjected to dynamic stresses
- Suitable substrate materials are metals, particularly aluminium (including anodised components), sheet steel (including phosphated, chromated and zinc-plated components), ceramic materials and plastics
