3M 7010045186 Weather Resistant Film Tape 838 White 4x72yd

Product Description

The 3M 7010045186 is a weather resistant film tape designed for demanding outdoor sealing applications. Constructed with a Tedlar PVF film backing and a pressure-sensitive acrylic adhesive, this tape measures 3.4 mil in total thickness. It is sold as a single roll measuring 4 inches wide by 72 yards long. The PVF backing provides resistance to UV exposure, moisture, and temperature cycling, making it well suited for exterior construction environments. Licensed contractors, glazing installers, and building envelope technicians are the primary installers for this product.

This tape is commonly applied to seal seams on outdoor building panels, exterior windows, and exterior doors where prolonged weather exposure is expected. It is also used as a hinge seal on shower doors and in similar severe-exposure applications where a durable, moisture-resistant bond is required. The acrylic adhesive system maintains adhesion across a range of temperatures and substrates common in commercial and residential construction.

Installation Notes

Installation is typically performed by glazing contractors, building envelope installers, or finish carpenters. Clean and dry the substrate thoroughly before application to ensure full adhesive contact. Apply firm pressure across the tape length using a roller or seam tool to seat the adhesive. Follow applicable local building codes and manufacturer surface preparation guidelines when using tape as part of a weather barrier assembly.
