CT1 Black - Sealant Adhesive - 290ml

CT1 is a unique, solvent-free sealant and adhesive based on TRIBRID Technology. It is engineered to bond and seal virtually any material in any condition—even underwater—making it one of the most versatile products in the construction, marine, and maintenance industries. CT1 is often referred to in the trade as the "Snag List Eliminator." It is a high-performance, universal sealant and construction adhesive that has largely replaced traditional silicones, PUs, and mastics in professional toolkits.

CHARACTERISTICS

• CT1 is the first of its kind to use this advanced formulation TRIBRID Technology, which makes it 360% stronger than traditional hybrid polymers. It offers superior colour retention (whites stay white) and enhanced resistance to bacteria and mould.
• Unlike standard sealants, CT1 works in the wet, dry, and even underwater. It is particularly effective for emergency repairs to leaking gutters, roofs, or marine vessels where surfaces cannot be dried.
  
• It remains permanently flexible, allowing it to withstand thermal expansion, contraction, and structural vibrations without cracking or losing its bond.
  
• It is solvent-free, odourless, and contains no isocyanates. It has been awarded the EC1 Plus certificate for the lowest indoor emissions and is approved by the NAAF (Norwegian Asthma and Allergy Association).
• Ideal for use in kitchens, cold stores, and clean rooms.
• Will not degrade or become brittle when exposed to direct sunlight.
• Maintains its volume after curing, ensuring a watertight seal.
• Can be painted over with most water-based paints once cured.
• Specifically suited for marine applications and coastal environments.
