New Sikaflex®-11 FC

Sikaflex®-11 FC is sold globally in over 100 countries for projects of every size.

The new Sikaflex®-11 FC Purform® builds on this legacy and will ensure that it is continued.

Sikaflex®-11 FC gets its versatility from the technology it’s made from: polyurethane!

Polyurethane offers the best balance of properties for general sealing and bonding in construction.

A durable strong bond or a permanent tight joint are the sum of properties such as adhesion, strength, elasticity, hydrolysis, chemical and UV resistance, tear resistance and many more.

Due to the unique microstructure of polyurethane, consisting of a polymer network with hard and soft elements, polyurethane can best meet all these requirements.

Other technologies, such as STP/MS, acrylics or silicones, may have specific advantages, but overall, for durable and long-lasting sealing and bonding, there is only one – polyurethane.

Sikaflex®-11 FC Purform® is made from the latest generation of polyurethane.
Purform® stands for “Pure”, “Polyurethane” and “Performance”. Purform® starts
at the very roots of polyurethane and gives us the control to engineer perfect and pure pre-polymers. These new building blocks are the core of the new
Sikaflex® products with ultra-low free monomer diisocyanate content.

Purform® polyurethane, through its simplicity, perfection and purity, has given our engineers the scope to develop the next generation multi-tool for sealing and bonding: Sikaflex®-11 FC Purform®.

Sikaflex®-11 FC Purform® impresses with faster curing, increased durability and less exposure to monomer diisocyanate content compared to the Sikaflex®-11 FC+ of today.

Sikaflex®-11 FC is a one-part, moisture-curing, polyurethane elastic adhesive and sealant.
