Kraft Joint PU 25 polyurethane adhesive sealant is a one-component thixotropic paste that cures on contact with atmospheric air, forming an elastic mass. It is used for sealing and bonding similar and dissimilar materials in buildings, in horizontal and vertical joints. It adheres to ceramics, concrete, glass, wood and galvanized sheet metal.
It is self-supporting, suitable for joints subject to significant movement, and can be painted with standard paints. It is resistant to UV radiation and moisture, and its recovery capacity exceeds 90%. It is certified to EN 15651.
