Premium 3M weather-resistant adhesive tape with Tedlar® PVF backing for outdoor sealing and protection applications. 6 inches wide, 72 yards per roll, 3.4 mil thickness, solvent-resistant acrylic adhesive, 8 rolls per case.
3M™ Weather Resistant Film Tape 838 is a premium industrial-grade adhesive tape designed for long-term outdoor exposure applications. This white tape features a strong, thin Tedlar® PVF Film backing combined with a high-shear solvent-resistant acrylic adhesive. The 3.4 mil thickness provides exceptional strength without adding bulk, making it ideal for sealing, protecting, and bonding applications in challenging environmental conditions. The tape maintains superior performance across a wide temperature range from -100°F to 225°F, ensuring reliability in extreme weather conditions.
This specialized tape is engineered with Tedlar® PVF Film backing that delivers increased strength without added thickness, providing excellent resistance to weathering and outstanding mechanical properties. The acrylic adhesive formulation offers immediate adhesion upon contact and maintains secure bonding for extended periods, even through climate and temperature variations. The tape demonstrates exceptional inertness toward a wide variety of chemicals, solvents, and staining agents, including jet engine fuel, hydraulic fluid, and lubricating oils, making it an excellent choice for aerospace, military, and industrial applications.
The Weather Resistant Film Tape 838 contains no plasticizers, contributing to superior long-term aging properties and durability. It is tough and flexible across a broad temperature range, making it suitable for diverse applications including sealing outdoor building panels, windows, doors, hinge seals on shower doors, and protecting critical areas from moisture intrusion. Each case contains 8 rolls of 72-yard tape, providing substantial coverage for large-scale projects and industrial operations.
