CT1 – Sealant & Adhesive

CT1 Sealant & Adhesive - available in 3 colours

CT1 sealant and adhesive is used for securely bonding things into place. A very versatile product that can be used both indoors and outdoors, which makes it a really popular multi-purpose sealant for repairs and construction. It's also UV-resistant, which means it won't fade or shrink when exposed to the sun. It's easy to use too; simply put the cartridge into a dispenser gun - there's no need for any extra fittings.

CT1 is an odourless product that is made without solvents or isocyanates. Once CT1 is fully cured, it can be painted with most water-based products. It's also vibration resistant, so it's ideal for high-traffic areas and places exposed to heavy winds. It's ideal for window and door surrounds, and is regularly used to repair fibreglass or carbon fibre boats. It even works underwater!

CT1 is the only product in the market with TRIBRID® Technology, which makes it 360% stronger than traditional hybrid polymers. It is scientifically proven to have superb colour retention – so the white version stays white and the clear version stays clear.
