C-Tec CT1 TRIBRID Multi-Purpose Sealant & Adhesive – 290ml (Box of 12)
CT1 is a true all-rounder and one of the most trusted sealants and adhesives on the UK market. Developed using revolutionary TRIBRID® Technology, CT1 delivers outstanding strength, flexibility and long-term durability, making it suitable for professional trade use as well as demanding DIY applications.
Its advanced formulation is scientifically proven to be up to 360% stronger than traditional hybrid polymers, while also offering exceptional colour retention. This means white stays white and clear stays clear, even when exposed to harsh or changing conditions.
Exceptional Bonding Performance Across Multiple Materials
CT1 is designed to bond securely to an incredibly wide range of materials, often without the need for additional fixings. It adheres confidently to metals (including lead), glass and mirrors, all types of wood and MDF, polystyrene, fibreglass, concrete and most stones without staining. It also bonds to many synthetic materials and plastics, with the exception of PP, PE and PTFE.
Thanks to its unique adhesion properties, CT1 delivers a reliable, long-lasting bond in situations where standard sealants and adhesives would normally struggle, making it ideal for sealing, bonding and emergency repairs.
