Metal Patches & Repair Materials

JB Weld can adhere to lightly corroded metal, but surface rust significantly reduces bond integrity. Tech-Bond's Filler and Bonding Agent system uses surface preparation steps — including Poly Prep and Activator — that promote molecular-level adhesion even on compromised metal surfaces, delivering a more durable and longer-lasting repair than conventional epoxy-based products.

Tech Patch and Tech Wrap Kits for Metal Pipes are available in seven widths: 2", 3", 4", 5", 6", 9", and 12". Each width offers multiple variants to match specific repair requirements, making the system adaptable for small residential pipe repairs up to large industrial tank patching applications.

Yes. The Tech Patch and Tech Wrap Kits are explicitly compatible with both metal pipes and tanks as well as PVC pipes. This dual compatibility makes them suitable for mixed-material systems commonly found in industrial facilities, utilities, and municipal infrastructure, reducing the need to stock separate repair products for different pipe materials.

Tech-Bond repair products are engineered for permanent repairs. The Polymer Bonding Process creates molecular cross-links rather than surface-level adhesion, resulting in bonds that are stronger than the original material. When properly applied following the TPRS system — including surface preparation with Poly Prep and Activator — repairs are designed to withstand chemical exposure, pressure, and harsh environmental conditions long-term.

Yes. Tech-Bond's Silica Sand Filler cures to a rock-hard mass that can be drilled, tapped, sanded, and painted. This makes it suitable not only for structural gap-filling on metal parts but also for finishing applications where the repaired surface must match surrounding material or accept fasteners, coatings, or further machining.

The Professional Kit bonds a wide range of challenging substrates including Delrin (POM), PTFE, HDPE, rubber, silicone, metal, and composites. The kit includes a choice of SI Blue, SI Black, or SI Green bonding agent, along with Poly Prep, Activator/Accelerator, Filler, and Debonder — providing a complete bonding lifecycle for field and shop use.
