Sikaflex-11 FC+
One-part multipurpose polyurethane elastic adhesive and joint sealant
Product Overview
Sikaflex-11 FC+ is a one-part, multipurpose elastic adhesive and joint sealant based on Sika’s i-Cure polyurethane technology. It cures with atmospheric moisture to a tough yet flexible rubber that both bonds components and seals movement joints, indoors and outdoors. The same cartridge handles structural-style bonding of concrete, masonry, stone, ceramic, wood, metal and glass, and the sealing of vertical and horizontal joints, with strong adhesion to many substrates without pre-treatment. Its high movement capability, good weathering resistance and very low emissions make it a versatile workhorse for construction, fit-out and maintenance teams who want one reliable product across many tasks. As an authorized Sika distributor in India, Space Arc Engineering supplies Sikaflex-11 FC+ in cartridges and foil packs with consistent stock for projects of every scale.
