Constructed with an extremely conformable backing, 3M™ polyethylene tape 480 is designed to be used in general repair, patching and splicing of polyethylene sheeting. This tape is coated with a non-yellowing, transparent, acrylic adhesive and features a clear polyethylene backing that helps make repairs less visible. Our 3M™ polyethylene tape 480 stretches easily and is highly conformable for a tight seal over and around irregular surfaces. The smooth backing provides good solvent and alkali resistance. It meets MIL STD 2041D(SH) for leachable halogens, making it ideal for corrosion sensitive applications. The acrylic adhesive bonds to a variety of surfaces and can be used in many sealing, protecting, repair and patching applications. This resilient tape can be used in short term outdoor applications at temperatures as low -20 °F and as high as 170 °F. Splicing and patching of polyethylene sheeting. Repairing awnings, sealing on smooth and irregular surfaces. Surface protection, short term outdoor repair applications. 3M™ 7000049617, 36 yd Length, 20 in Width, 5.1 mil Thickness, Transparent, Acrylic Adhesive, Polyethylene Backing, 22 in-oz Adhesion Strength, 12 in-lb Tensile Strength, 170 °F Maximum Operating, 20 °F Minimum Operating, Specifications Met: ASTM D3330/D3759/D3652
