Fabric Adhesives

The best solution depends on the material. For polymers, PTFE-coated fabrics, HDPE, nylon, or silicone-based materials, Tech-Bond's SI Bonding Agent outperforms conventional glues by creating a molecular-level cross-linked bond. Traditional adhesives fail on low surface energy substrates; Tech-Bond's system, especially when used with Poly Prep surface preparation, delivers a permanent, field-proven bond.

Tech-Bond's SI Bonding Agent bonds fabric to fabric at the molecular level, particularly effective on PTFE-coated fabrics, composite textiles, and polymer-backed materials. Use SI Blue for standard fabric joins, SI Green for thin-seam or hairline bonding, and apply Poly Prep first when bonding low surface energy fabrics like PTFE or polypropylene to ensure maximum adhesion and permanent hold.

For a permanent fabric-to-fabric bond, start with Poly Prep adhesion promoter to etch and activate the surface, then apply the appropriate SI Bonding Agent viscosity — SI Blue for standard joins or SI Green for fine-seam work. Adding the Activator/Accelerator speeds cure time and enhances cross-linking. This patented process creates bonds stronger than the original material, tested and validated by IIT (ISM) Dhanbad.

Choose SI Blue (thin-medium) for general fabric bonding and broad surface coverage. Use SI Green (ultra-thin) when bonding delicate fabrics, fine seams, or hairline cracks where deep penetration is needed. SI Black (thick) is best for controlled application on overhead or vertical fabric surfaces where you need the adhesive to stay precisely in place during cure.

Yes. Tech-Bond's system is specifically engineered for low surface energy materials including PTFE, nylon, polypropylene, and HDPE — materials that conventional adhesives cannot bond. The Poly Prep adhesion promoter etches the surface to enable adhesion, and the SI Bonding Agent then creates a permanent molecular bond. This combination has been validated through ASTM testing and IIT (ISM) Dhanbad research.

Tech-Bond's Professional and Deluxe Kits include everything needed for a complete bonding job: an SI Bonding Agent (choice of Blue, Black, or Green viscosity), Poly Prep surface preparation solution, Activator/Accelerator catalyst, Filler for gap reinforcement, and a Debonder for clean removal if needed. Starter and Basic Kits offer the bonding agent alone for simpler repair tasks at a lower entry price.
