    3M™ Polyurethane Adhesive Sealant 540 is a one component, polyurethane designed as a flexible sealant for transportation, metal working and many other applications.

    Use 3M™ Polyurethane Adhesive Sealant 540 to seal vertical and horizontal expansion joints, aluminium curtain walls and storefronts, doors and windows, submerged applications and much more. Our high performance, one component, moisture curing sealant forms permanently elastic bonds, and is non-staining. It’s fast curing, and no mixing or priming is required for most applications. Tack-free in 60 minutes, the sealant is then paintable and offers excellent weather resistance. The sealant is available in a range of colours, including white, tan, bronze, grey and black. Additional colours are available for larger orders.
