SIKAFLEX® AT CONNECTION – The flexible one, 20x600 ml

Sikaflex® AT Connection is an outstanding one-component, isocyanate-free sealant based on silane-terminated polymer for civil engineering and building construction. It cures by reaction with atmospheric moisture to form an elastic sealant. This sealant is particularly suitable for use in living spaces, public buildings, schools and nurseries, as it is solvent-free and odour-neutral.

Application:

Thanks to its excellent adhesion to porous and smooth substrates, Sikaflex® AT Connection is ideal for connection joints in building construction. This includes windows and doors, roller shutter boxes, facades in metal construction, metal claddings and plastic components indoors and outdoors. Its suitability in accordance with the RAL installation guide deserves particular mention.

Sikaflex® AT Connection is also used for certain fire-rated joint seals in horizontal and vertical building elements.

Advantages:

• Very high UV resistance and colour stability
• Primerless application on many metals and plastics
• Particularly suitable for connection joint sealing in accordance with the RAL installation guide
• EMICODE EC1PLUS, very low emission
• Solvent-free
• Very good application properties, especially tooling and extrusion behaviour
• Very broad adhesion spectrum on porous and smooth building materials
• Permissible total deformation 25%
