Believe it or not, 3M, today’s leading manufacturer of marine adhesives, sealants, and cleaners, was initially founded as a mining venture to mine corundum. The folk behind the company found out that the mineral they thought was corundum was actually anorthosite. Instead of calling it a day, the founders changed the goal of the company. These days, 3M marine adhesives and sealants along with cleaners, polishes, and protectors are globally known for their high quality, and durability and used by boaters all around the globe.
Whether you are going to repair or maintain your boat or build a new one, the brand has the right products to be used below or above the waterline. Depending on your needs, you can go with a urethane, synthetic rubber, nitrile, or acrylic adhesive sealant. Keep in mind that the company's offerings have different tack-free and full cure times. All of them are formulated to resist harsh marine environments including UV-rays, vibrations, swelling, shrinkage, etc. The company is probably best known for its polyurethane polymer adhesive sealant 5200. It is developed to be used when permanent bonding of fiberglass, wood, gelcoat, and the like is required. It remains flexible after curing allowing for structural movement caused by swelling, shrinking, vibrations, etc.
