Multi Material Adhesives

Tech-Bond's Professional Kits are a prime example of a multipart adhesive system. Each kit includes a SI Bonding Agent (Blue, Black, or Green viscosity), Poly Prep adhesion promoter, Activator/Accelerator, Filler for gap reinforcement, and a Debonder — providing a complete, staged bonding process that ensures maximum adhesion on even the most difficult materials.

Tech-Bond's SI Bonding Agents, used with the full Polymer Bonding Process, represent the ultimate multi-surface adhesive system. They bond PTFE, HDPE, Delrin, silicone rubber, nylon, polypropylene, metals, wood, and composites at the molecular level. Unlike conventional adhesives, this patented process creates permanent crosslinks that are stronger than the original material — proven in industrial, field, and engineering environments globally.

Tech-Bond adhesives bond a wide range of difficult-to-bond materials including PTFE (Teflon), HDPE, Delrin (POM), polypropylene, nylon, silicone rubber, metals, composites, wood, and pot metal. The patented Polymer Bonding Process enables molecular-level bonding on low surface energy polymers that conventional glues and cyanoacrylates cannot effectively adhere to.

Yes. For polymers and low surface energy plastics, applying Poly Prep Adhesion Promoter before bonding is essential. Poly Prep etches the surface to create the right micro-texture for strong adhesion. This step significantly increases bond strength on materials like PTFE, HDPE, nylon, and silicone rubber. After Poly Prep, apply the SI Bonding Agent and Activator/Accelerator for a complete, permanent bond.

Choose SI Blue (thin-medium) for standard bonding tasks and general-purpose applications. Use SI Black (thick) when you need greater control during application, particularly on vertical surfaces or in overhead environments. SI Green (ultra-thin) is specifically designed to penetrate and repair hairline cracks in plastics and polymers. All kits are available with your choice of viscosity to match your specific task.

Yes. Tech-Bond Professional Kits are specifically built for both shop and field use, requiring no special equipment for application. The included Activator/Accelerator enables fast cure times suitable for on-site repairs. Kits have been successfully deployed in extreme industrial environments including mining, energy infrastructure, and marine settings globally, making them reliable for emergency and planned field repair operations.
