3M™ Controlled -Flow Seam Sealer 200mL Cartridge

3M™ Controlled-Flow Seam Sealer offers considerable strength, flexes under torsional stress from vibration and withstands extreme weather. The urethane formula contains no solvents and will not shrink or crack. These characteristics make it an ideal choice for automotive applications where motion and exposure to weather are a constant factor. Tough, Flexible and Self-Leveling, 3M™ Controlled-Flow Seam Sealer uses two-part urethane technology to provide a tough flexible material for the sealing of joints on primed or painted substrates such as steel or aluminum enclosures. 3M™ Control-Flow Seam Sealer works particularly well in areas where a flowable self-leveling type seam sealer is required. It is designed to flow one to two inches and then begins to cure, preventing further flow out of the material. This feature allows the user to control the application, preventing excessive waste while maintaining a uniform film thickness even on surfaces that are not level. Typical product uses include automotive “roof ditch” applications where a flow grade sealer is required and some “trunk rain gutter” seams where the use of a standard “self leveling” sealer is unacceptable due to flow characteristics. This urethane base auto body seam sealer has a paste consistency and is black/amber in color. This 3M seam sealer offers a 3-minute work time, cures in 2 hours and is ready for painting in about 40 minutes, depending on environmental conditions.
