## Description

At C-Tec, we have a mission to eliminate all the inconveniences of conventional sealants while eliminating the need for different types of sealants. To surprise from the market we achieved this goal eight years ago. When we created the only CT1 construction sealant and adhesive, the development in the field of sealants was unprecedented, as was the unique formulated compound, the heart of which is a hybrid polymer. CT1 replaces at least seven different types of products and has none of the disadvantages of conventional sealants and adhesives. For example, CT1 sealant can be applied to a wet surface even under water. Unlike traditional silicone sealants, it can be painted or textured, making it an ideal solution for repairing cracks where fillers fail. It is an adhesive and sealant that perfectly repairs the roof and sticks lead to bricks or felt to wood. CT1 sealant is the safest for the environment. It is 100% free from volatile organic compounds, does not contain petrochemicals. This allows the CT1 sealant to be accredited with a European food approval certificate. This incredible adhesive and sealant is extremely versatile and expands up to 350% without breaking and has an incredible strength of 270 n/cm², comparable to an aluminium weld.The CT1 sealant is available in several colours: transparent, white, black, grey, beige, brown, oak, blue and silver. -
