ARDA SEAL PU-40 – Polyurethane Construction Sealant

ARDA Seal PU-40 is a single-component, medium-modulus polyurethane sealant that cures by reacting with atmospheric moisture. It delivers excellent adhesion to a wide range of construction substrates including cement-based materials, brickwork, ceramics, glass, wood, galvanized and painted metal surfaces, as well as various plastics. Once cured, it forms a durable, elastic seal suitable for demanding construction applications.
