CT1

Most conventional sealants and adhesives struggle when it comes to bonding and sealing in difficult environments—especially underwater. CT1 has completely transformed this space by introducing a powerful, user-friendly formula that works effectively even in fully submerged conditions. From swimming pools and marine repairs to plumbing and emergency fixes, CT1 delivers strength, durability, and consistent results where others fail.

CT1’s true value goes beyond just underwater performance. It stands out as a genuinely multi-purpose solution capable of bonding virtually any material, across countless applications, without relying on additional mechanical fixings. This versatility is what has earned CT1 the title of the UK’s number one sealant and adhesive among professionals.

Introduction to CT1 and TRIBRID® Technology

CT1 stands out as a truly unique sealant and construction adhesive, built upon the foundation of the revolutionary TRIBRID® polymer technology. This advanced formulation is the cornerstone of CT1's exceptional performance, providing significant advantages over conventional sealants and adhesives available today.

Thanks to its innovative composition, CT1 offers outstanding flexibility, superior strength, and remarkable durability even under the most challenging conditions. It bonds successfully to virtually any material — including metals, glass, wood, concrete, ceramics, and most plastics — without the need for additional primers or preparation. Unlike traditional adhesives, CT1 remains permanently flexible, ensuring a long-lasting, resilient seal that can withstand movement, vibration, and extreme temperature changes.

Moreover, CT1 is completely eco-compliant, boasting a solvent-free formula that is safe for use in sensitive environments such as hospitals, schools, and food preparation areas. Its resistance to mold, mildew, and bacteria further enhances its reliability in both indoor and outdoor applications.

CT1 also performs exceptionally well underwater, making it the ideal solution for marine and bathroom sealing, as well as emergency repairs in wet conditions. Its unparalleled weatherproofing and UV resistance mean it maintains its integrity and appearance over time, even when exposed to harsh environmental factors.

In short, CT1’s cutting-edge TRIBRID® technology redefines what is possible in sealant and adhesive performance — delivering unmatched reliability, versatility, and peace of mind across countless industries and applications.

The Power of TRIBRID® Technology

The outstanding performance of CT1 is driven by its cutting-edge TRIBRID® polymer technology — a breakthrough that marks a new era in adhesive and sealant innovation. Developed through extensive research and engineering, TRIBRID® technology builds upon the strengths of previous generations, including silicones, traditional polymers, MS polymers, and hybrid polymers, while eliminating many of their common weaknesses.

Unlike earlier technologies that often forced users to compromise between flexibility, strength, or durability, TRIBRID® offers an exceptional balance of all three. It delivers superior bonding strength, enhanced elasticity, and extraordinary resistance to environmental factors such as UV radiation, chemicals, and weathering.

Furthermore, TRIBRID® technology ensures CT1 is highly resistant to shrinkage, discoloration, and cracking over time, even under extreme conditions. Its formulation provides a longer-lasting seal and stronger adhesion across a wider variety of materials, including metals, plastics, wood, concrete, and even wet surfaces — all without the need for primers.

Thanks to the innovation of TRIBRID®, CT1 not only meets but exceeds the performance expectations of modern construction, repair, and industrial projects, providing professionals and DIY users alike with a truly universal solution. Whether it's demanding structural bonding, sensitive installations, or emergency repairs, CT1 powered by TRIBRID® technology offers reliability, versatility, and lasting results like no other product on the market.

Outshining Standard Hybrid Sealants with TRIBRID® Technology

CT1, powered by advanced TRIBRID® technology, raises the bar far above standard hybrid sealants, delivering outstanding performance where it matters most:

  • Unmatched Strength: Once cured, CT1 reaches an exceptional tensile strength of around 304 Newtons per square inch, providing a tough, reliable bond that professionals can trust.

  • True Color Stability: Unlike many white sealants that discolor or yellow with age, CT1 preserves its fresh, clean appearance over time, ensuring a flawless and lasting finish.

  • Outstanding Chemical Resistance: Designed to perform in tough environments, CT1 resists a wide range of aggressive substances — including diesel, petrol, and oils — making it the perfect choice for industrial, automotive, and heavy-duty applications.

  • Zero Shrinkage, Zero Cracks: Thanks to its solvent-free and isocyanate-free formula, CT1 won't shrink, crack, or deteriorate, guaranteeing a bond or seal that stands the test of time.

With CT1, you're not just getting a sealant — you're investing in next-generation performance and durability.
