TRIBRID® Technology: The Next Evolution

For years, hybrid polymers were the industry standard for grab adhesives and sealants. CT1 has rewritten the rulebook with its revolutionary TRIBRID® Technology. This advanced chemical structure makes CT1 a staggering 360% stronger than traditional hybrids. It provides such immense initial grab and ultimate tensile strength that, in most applications, you can completely eliminate the need for mechanical fixings like screws or nails. Furthermore, this unique formulation guarantees superior colour retention, meaning your white bathroom seals won't yellow and your clear glass joints won't turn cloudy over time.

Unrivalled Marine & Underwater Performance

When a pipe bursts or a boat hull needs an emergency patch, you rarely have the luxury of waiting for the surface to dry. CT1 is famously renowned for its ability to perform flawlessly in the presence of moisture. It will instantly bond and seal in wet conditions, and can even be applied entirely underwater. Perfectly suited for salt-water environments, it is the ultimate essential tool for boating maintenance, plumbing emergencies, and fast-track exterior repairs in harsh weather. It even provides instant bonding for advanced materials like fiberglass and carbon fibre.

Supreme Safety for Any Environment

Heavy-duty adhesives usually rely on harsh, noxious solvents. CT1 breaks this mold entirely. It is completely solvent-free, entirely odourless, and boasts an EC1 Plus A+ Indoor Air Comfort GOLD® rating, making it incredibly safe to use in enclosed or poorly ventilated spaces. Its hypoallergenic properties are officially approved by the Norwegian Asthma and Allergy Association. Beyond residential safety, it is also ISEGA Certified, meaning it strictly conforms to safety standards for use in commercial kitchens, hospitals, and food preparation areas.

No. Unlike traditional silicone sealants which can leach oils into porous natural stone, CT1 is formulated to be non-staining, making it perfect for high-end kitchen and bathroom installations.

Can I paint over the sealant once it dries?

Yes, CT1's unique flexibility and solvent-free nature allow it to be painted over. It is recommended to test a small area first, depending on the specific type of paint you are using.
