3M™ Polyurethane Sealant 540(pc)

3M™ Polyurethane Sealant 540 is a single-component polyurethane sealant designed for bonding and sealing work where a durable, flexible joint is required. It cures in the presence of moisture and can join different types of materials without requiring a separate mixing step. The cured sealant remains elastic, allowing the joint to accommodate movement and differences in thermal expansion between bonded materials. It is suitable for a broad range of industrial, construction, transportation and related applications.
