CT1 is the ultimate solution for sealing and bonding. It will successfully bond with almost any material without the need for additional fixings – this powerful sealant and construction adhesive won’t let you down.
Completely odourless and highly flexible, CT1 grey sealant always performs well under extreme pressure without cracking or shrinking. It’s also perfect for instant repair and bonding with fibreglass and carbon fibre materials.
Made using TRIBRID® technology, CT1 Grey is more powerful than a regular sealant and far stronger than other hybrid polymers. This increased adhesion power excels with metal, concrete, glass, and wood as well as many other materials, and its UV resistance offers excellent colour retention – once applied, grey CT1 stays grey.
