CT1 TRIBRID Sealant and Adhesive for Multi-Surface Construction Use

One Product, Many Applications:

CT1 is marketed by the manufacturer as "The Snag List Eliminator" for good reason. Its TRIBRID® Technology replaces a wide range of conventional products, including wood and PU adhesives, silicone sealants, acrylic sealants, sanitary sealants, and butyl rubber sealants, reducing the number of products needed on site or at home.

TRIBRID® Technology - Exceptional Bond Strength:

The proprietary TRIBRID® formulation delivers a substrate bonding tensile force of 3.07 N/mm² and achieves 385% elongation at rupture, so it flexes without failing even under significant movement or vibration. Independent testing to BS EN ISO 8339:2005 confirmed strong adhesion on virtually any material without additional mechanical fixings.

Works in Wet Conditions:

CT1 can be applied to damp surfaces and will even cure and bond underwater, making it well suited to gutter repairs, bathroom panels, and marine applications. Its curing system is neutral cure and completely solvent-free, with no isocyanates, and is certified to EC1 Plus A+ Indoor Air Comfort GOLD® standard.

Mould Resistance and Long-Term Performance:

TRIBRID® Technology inhibits the growth of bacteria and mould on the cured surface, which is particularly useful in kitchens, bathrooms, and other humid environments.

Eco-Compliant and Certified:

Each CT1 cartridge is manufactured from 80% recycled materials. The product carries ISEGA certification confirming it meets food preparation standards, and it is approved by NAAF - the Norwegian Asthma and Allergy Association. It meets ISO 11600 25HM and ETAG 022 Annex E, B and F standards.
