## Description

3M Marine Adhesive Sealant 5200 is a tough, flexible polyurethane for permanent bonding and sealing your RV, boat or other watercraft.

It applies right from the container – no mixing is required. It becomes tack-free in 48 hours, and cures to form a firm, flexible, waterproof seal on joints and boat hardware.

In fact, for more than 50 years, 3M Marine Adhesive Sealant 5200 has been used and trusted as a marine sealant by professionals in some of the most demanding conditions on earth. Polyurethane sealants provide strong, flexible durable elastomeric bonds that seal against the elements. These sealants excel in challenging industrial, transportation and construction applications. Polyurethane sealants are available in a wide variety of Shore A hardness, open time and colors to meet many application needs.
