Our 3″ 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 3″ wide 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 MUST extend one inch beyone the crack or tear around the entire perimeter of the damage.
3″ wide Tech Patches and Tech Wraps
Tech-Bond’s Tech Patches and Tech Wraps provide a versatile repair solution for medium-diameter pipes and tanks, offering greater surface coverage than the 2″ versions without sacrificing flexibility or ease of application. Made from PTFE-coated E-glass fabric and applied using the Polymer Bonding Process, these 3″ wide products deliver permanent repairs that resist chemicals, moisture, UV, and extreme temperatures. The wider format ensures enhanced structural reinforcement and bonding strength, especially in situations where added coverage or wrap overlap is critical. Ideal for industrial, agricultural, and utility applications, they are compatible with both metal and polymer substrates, including steel and HDPE.
