Derby PU Sealant is a single-component, polyurethane-based sealing material that cures with moisture in the air. It offers excellent heat resistance, functioning effectively between -40°C and +90°C, and can withstand short-term temperature variations up to +120°C. Once cured, this sealant can be painted over, making it versatile for various applications. It is ideal for automotive spare part applications, filling joints in walls and precast concrete, and providing insulation for materials such as metal, aluminum, glass, wood, and plastic. Additionally, it ensures watertight seals in ventilation systems, rainwater collection pipes, and gutters.
