Sazilast 25 (grey label) — polyurethane sealant for facade joints
The grey-label version of Sazilast 25 is a two-component non-shrinking polyurethane sealant for facade panel joints. The cured joint can be painted with both water-based and solvent-based facade paints. Joint movement is up to ±25%, elongation at break is at least 350%, service is from −60 to +70 °C, and the predicted service life is 15 conventional years. The technical description expressly excludes roof elements and joints designed for prolonged contact with water.
