Duck Brand T-REX Duct Tape is a 17 mil thick ferociously strong specialty-grade cloth metallic silver duct tape. A double layer of quick stick adhesive is combined with extra strong cloth and a durable waterproof film layer to create the solution for all of your toughest repairs. Typical applications of TREX Duct Tape include bonding to rough surfaces; heavy repairs; and for use as bottom board tape in manufacturing housing.
Duck Brand/Shurtech makes the tape in 3 layers. Layer 1 is the tough, thick polyethylene skin which repels even the harshest elements. Layer 2 is the thick heavy thread which is tightly and securely interwoven which creates a reinforced inner cloth. Then layer 3 is the double-adhesive which melts through layer 2 and locks onto layer 1 via co-extrusion. It equates to 4x the staying power, 3x the holding power, and 2x the bite of regular duct tapes. TREX comes with Shurtech's Polyblended CO-EX technology with is a co-extrusion process which melds polyethylene, cloth and adhesive in a single, high-temperature step which results in a permanent, airtight bond (creates added strength which will not delaminate). Made in the U.S.
