Professional gray sealing tape with TPO backing for quick, clean outdoor sealing. Resistant to sun, rain, extreme temperatures, and vibration. Eliminates messy caulking with instant adhesion and water-tight seal.
3M™ Extreme Sealing Tape 4410G+ is a professional-grade sealing solution designed for quick and clean sealing applications in demanding outdoor and industrial environments. This gray, 0.025 inch (0.6 mm) thick tape features a durable thermoplastic polyolefin (TPO) backing with a permanent acrylic adhesive that delivers instant adhesion to metals and plastics. The tape is engineered to overcome challenges of sealing out water, dust, dirt, and other environmental factors, making it ideal for cargo trailer rail seals, HVAC enclosures, roof sealing, and general industrial applications.
The tape's rugged construction provides exceptional resistance to sun, rain, and extreme temperatures ranging up to 200°F (93°C), while maintaining flexibility to conform over fasteners, seams, joints, holes, and gaps. Unlike traditional liquid sealants, this linerless design eliminates the need for caulking applicators, cartridges, cure time, mess, and oozing. The single-coated, conformable backing ensures a water-tight seal that resists vibration, thermal expansion, and contraction, making it suitable for both interior and exterior applications across construction, general industrial, MRO, metalworking, signage, solar, specialty vehicles, and transportation industries.
Each case contains 3 rolls of 36-yard length tape, providing comprehensive coverage for large-scale sealing projects. The product features UV resistance, humidity resistance, and low temperature resistance, supporting sustainability goals through its linerless design that eliminates traditional liner waste. With a 24-month shelf life and available in multiple colors and thicknesses, this tape is the go-to solution for professionals seeking reliable, durable, and efficient sealing solutions.
