Tested, certified, proven

This adhesive comes in particularly useful when the materials in question are exposed to UV radiation and inclement weather. Due to its excellent adhesion to glass, our 670 2K-Kleber can be used for sealing insulating and single-pane glass. It is also suitable for anti-burglar RC2 and RC3 bonds. Its exceptional resilience makes it suitable for industrial applications, too, such as shipbuilding and car manufacturing. As the adhesive is based on a fast-cure, moisture-tolerant, two-component silicone rubber, it applies extra-efficiently. It is also neutral-cure with minimal shrinkage. The product can be used as a UV-resistant secondary compound in the production of insulating glazing.
