Metal Bonding Adhesives

Tech-Bond's Polymer Bonding Process enables permanent metal bonding without heat or welding equipment. Apply the Poly Prep surface preparation, follow with the SI Bonding Agent, and use the Activator/Accelerator to cure the bond at the molecular level. The resulting joint can be drilled, tapped, sanded, and painted — matching or exceeding the strength of the base material.

For metal panel bonding, Tech-Bond's SI Black (thick viscosity) bonding agent offers superior control on vertical or overhead surfaces, preventing run-off during application. Paired with the silica sand Filler for gap bridging and the Activator/Accelerator for fast cure, it provides a durable, paintable bond ideal for automotive, industrial, and construction panel repair.

Yes. Tech-Bond's Filler — a silica sand compound — is specifically designed to fill cracks, gaps, stripped screw holes, and missing material in metal, wood, and composites. When layered with the Bonding Agent, it forms a rock-hard mass that can be drilled, tapped, sanded, and painted after curing, restoring full structural function.

Choose SI Green (ultra-thin) for hairline cracks where deep capillary penetration is needed. Use SI Blue (standard thin-medium) for general-purpose metal bonding and maintenance tasks. Select SI Black (thick) when you need maximum application control on vertical surfaces, overhead joints, or larger gap areas where runoff must be prevented.

Yes. The Tech Patch and Tech Wrap Kits for Metal Pipes are purpose-built for repairing leaking or damaged metal pipes and tanks, as well as PVC piping. Available in widths from 2" to 12" as part of the TPRS (Tech Patch Repair System), these kits are used in industrial, utility, and infrastructure settings for emergency and scheduled maintenance repairs.

Tech-Bond bonding agents have an extended shelf life when stored correctly. After opening, store the product in a refrigerator to maximize usability and slow degradation. Always bring the product back to room temperature before use to ensure optimal viscosity and bonding performance. Bulk and multi-pack options are available for high-volume users.
