3M Completes Advanced Weathering Research on Marine Sealants

Results helped 3M increase the durability and cosmetic appeal of Marine Sealants above and below the waterline

Hours in the sun and the effects of water and humidity can take a toll on boats. When the need for repair arises, it can be difficult to find a product that provides a lasting seal against leaks while matching the seamless look of the vessel. To better predict how long a product will last under these harsh conditions, 3M tests the weatherability of all its marine adhesive sealants. Recently, 3M completed new extensive weatherability testing on its 3M™ Marine Adhesive Sealant 4000 UV in both black and white formulations to ensure durability and performance in harsh conditions.

 

3M Marine Adhesive Sealant 4000 UV underwent significant testing while being developed to maximize UV stability and prevent fading, chalking and cracking. 3M’s portfolio of marine adhesive sealants are designed with the flexibility to help dissipate stress caused by shock, vibration, swelling or shrinking, and are also ideal for bedding applications on fiberglass hulls, sealing around porthole frames and screw holes, through-hull and deck hardware.

 

“Through our proprietary weatherability tests, we can accurately predict how marine sealants will stand the test of time even when exposed to harsh conditions,” said Peter Rebstock, U.S. Marketing Manager for Sealants at 3M. “Durability is a 3M promise, and the results of our research directly impact the formulation and science behind our adhesives.”

 

3M performs its state-of-the-art testing at the Weathering Research Center (WRC) in St. Paul, Minn. The WRC is the world’s largest single-site accelerated weather facility. At this laboratory, specialized technology is used to simulate the climate of south Florida. That region is generally considered to experience the harshest weather conditions in the United States for boat sealants, including intense exposure to heat, water, UV rays, humidity and wind.
