CT1 Unique Sealant & Construction Adhesive - Black 290ml

CT1 Black is a high-performance sealant and construction adhesive powered by C-Tec's proprietary TRIBRID technology. It bonds and seals virtually any material to any material, replacing the need for multiple products on site. From metal and glass to wood, concrete, and most plastics, CT1 provides a strong, flexible bond that holds up under demanding conditions.

The black formulation offers excellent colour retention, staying true black over time even with UV exposure. This makes it the obvious choice for anthracite window frames, black guttering, dark-finish metalwork, and any application where a clean, dark joint line is required.

TRIBRID technology gives CT1 up to 360% more strength than traditional hybrid polymer sealants, combined with 250% greater flexibility. It works in wet and dry conditions and will bond underwater, making it suitable for marine, plumbing, and exterior applications. CT1 is solvent-free, odourless, contains no isocyanates, and resists mould and bacterial growth without fungicidal additives.
