Metal Hole Fillers for Patching & Repair

Tech-Bond's no-weld approach uses a silica sand Filler compound mixed with a Bonding Agent to fill and rebuild damaged metal areas. For pipe and tank repairs, Tech Patch and Tech Wrap Kits wrap around the damaged section, bonding at the molecular level to restore structural integrity. No heat, no special equipment, and no downtime are required.

JB Weld is a common epoxy-based filler, but it relies on adhesive bonding rather than molecular crosslinking. Tech-Bond's Filler compound, used with its proprietary Bonding Agent, forms a harder, more durable repair that can withstand drilling, tapping, and painting. For critical metal pipe or tank repairs, the Tech Patch Repair System offers a validated, pressure-rated alternative.

The silica sand Filler compound is compatible with metal, wood, composites, and pot metal. It is not recommended for polymers or plastics, where gap filling performance is limited. For polymer repairs, Tech-Bond offers dedicated bonding kits including the Deluxe Kit, Professional Kit, and Poly Kits with appropriate Bonding Agents.

Tech Patch and Tech Wrap Kits are available in seven widths: 2", 3", 4", 5", 6", 9", and 12". Each width has multiple variants to suit specific repair applications. This range covers everything from small-diameter residential pipes to large industrial pipelines and containment vessels.

Yes. Once fully cured, Tech-Bond's silica sand Filler compound can be drilled, tapped, sanded, and painted. This makes it suitable not only for structural gap filling but also for cosmetic finishing and functional rebuilding of threaded holes or worn surfaces on metal parts and assemblies.

Yes. Tech-Bond's patch kits and filler systems are designed for both field and shop deployment. No specialized equipment or heat sources are required. The Tech Patch Repair System has been proven in demanding field environments, including the repair of a 78-inch HDPE pipe for Borouge in Abu Dhabi, demonstrating reliability under extreme conditions.
