Polyurethane adhesive sealant
SIKA Sikaflex-11 FC Purform White PU Adhesive Sealant 600 ml
Bonds and seals in one step — indoors and out, on almost any surface.
SIKA Sikaflex-11 FC Purform is a multi-purpose polyurethane adhesive and joint sealant in a 600 ml cartridge that bonds and seals at the same time. It grips firmly on concrete, masonry, natural stone, ceramics, wood, metal and glass. The formula works equally well on interior and exterior joints and connections.
Bonding and sealing in one step
Sikaflex-11 FC Purform combines strong bonding and flexible sealing in a single product, so you skip a second compound on site. It joins most construction substrates — concrete, masonry, stone, ceramics, wood, metal and glass. Ideal where two different materials meet.
Elastic joint that absorbs movement
The cured joint stays permanently flexible and springs back after stretching, with elastic recovery of about 85%. This keeps the seam from cracking under thermal movement and vibration. Suitable for both horizontal and vertical joints.
Easy application with no sag
Sikaflex-11 FC Purform applies smoothly with a standard caulking gun and does not slump on vertical surfaces. It cures bubble-free and reaches a tensile strength of around 1.8 N/mm². Good weather resistance makes it reliable indoors and outdoors.
Low emissions for a healthier space
Sikaflex-11 FC Purform is solvent-free and virtually odourless, with very low emissions rated EC1PLUS R. That makes it a safe choice for enclosed interior rooms. It fully cures to about 100% after 3 days at +23 °C.
