Black sealing tape 3M 4411B+ Extreme, 1mm, 50mm*33m

3M™ Extreme Sealing Tape 4411B+ (1.0 mm, 50 mm x 33 m, black) is a high-performance, translucent-to-black acrylic sealing tape designed to instantly seal over existing seams, joints, holes, and fasteners. Featuring a thick, durable, yet highly conformable acrylic backing and an aggressive acrylic adhesive, this tape creates a permanent, waterproof seal that resists harsh weather, UV radiation, and extreme temperatures. It steps over contours, rivets, and screw heads effortlessly without tearing or lifting. Ideal for demanding outdoor sealing applications in transportation, manufacturing, roofing, and trailer construction where mechanical fasteners alone are not enough.
