Tech Patch/Tech Wrap 6″ wide | PTFE coated E-glass Frabric

Our 6″ wide Tech Patches and Tech Wraps use PTFE-coated E-glass fabric. This material combines the strength and heat resistance of E-glass with the chemical resistance and low friction of PTFE. We treat the fabric using Tech-Bond’s proprietary activation process. This process permanently changes the surface energy. As a result, the fabric bonds directly to metals, HDPE, polypropylene, and other hard-to-bond surfaces. No sanding, priming, or fasteners are needed. The material stays strong, flexible, and reliable in tough environments. It’s ideal for repairs, insulation, containment, and reinforcement.

Tech-Bond’s Tech Patches and Tech Wraps are designed for precise, field-ready repairs on pipes, tanks, and structural surfaces. Their narrow width makes them ideal for targeted reinforcement, sealing linear cracks, or wrapping around tight curves and small-diameter pipes. When used with the Polymer Bonding Process, they create a permanent, flexible bond that resists heat, chemicals, pressure, and UV exposure. These 2″ solutions offer a fast, durable option for technicians who need reliability in demanding conditions.

Please note that an A-Patch/Wrap, like our 6″ wide Tech Patches and Tech Wraps” MUST extend one inch beyone the crack or tear around the entire perimeter of the damage.
