Product Details

3M Polyurethane Adhesive Sealant 550

3M Polyurethane Adhesive Sealant 550 is a single component polyurethane-based sealant.  Polymerization is very quick and the compound remains permanently elastic and waterproof after curing.  Unlike Silicone Sealants, 3M Polyurethane Adhesive Sealant 550 can be painted over.  It is good for jointing and bonding in metal constructions and floor-joints, especially those subjected to heavy traffic.  The cured compound has excellent resistance to chemicals and mineral oils.
