Powered by TRIBRID® Technology, it delivers up to 360% greater strength than a traditional hybrid polymer and 250% more elongation, bonding to virtually any material without the need for additional mechanical fixings. Bonds in Wet Conditions and Underwater: CT1 Black can be applied directly onto damp surfaces and will bond effectively even when submerged underwater - a performance level no standard silicone or acrylic sealant can match. Skin formation takes approximately 24 minutes, with full cure achieved within 48 hours under standard conditions. Cure time varies with temperature, humidity, and joint thickness. Certified Safe for Indoor and Food-Adjacent Use: CT1 is 100% VOC-free and contains no petrochemicals or solvents, making it completely odourless during application. It holds the EC1 Plus A+ Indoor Air Comfort GOLD® certification, is approved by NAAF (Norwegian Asthma and Allergy Association), and carries ISEGA certification for conformity to food preparation standards. Once cured, it operates reliably between -40°C and +120°C and can be overted with most water-based ts. Durable, UV-Stable, and Long-Lasting in Black: The black colour is UV-resistant and retains its depth over time - it will not yellow or fade as many lesser sealants do. CT1 is also resistant to fungal and bacterial growth, vibration, and movement, making it a reliable choice for roofing, marine repair, construction joints, and general maintenance tasks. Each cartridge is supplied in eco-compliant packaging made from 80% recycled materials. Shop our full ting & Decorating range from Heavins.ie, with delivery available across Ireland.
