Polyester & Polyurethane Repair Kits

Yes. Tech-Bond Global's SI Bonding Agent kits are formulated to chemically bond polyurethane and similar polymers at the molecular level. Unlike standard adhesives that sit on the surface, the Tech-Bond process crosslinks the polymer substrate itself, creating a permanent, high-strength repair. Select the appropriate viscosity — SI Blue for standard repairs, SI Green for hairline cracks — based on the damage profile.

Standard epoxy adhesives like JB Weld typically do not bond reliably to polyethylene, PTFE, or other low-surface-energy polymers because they rely on surface adhesion rather than molecular bonding. Tech-Bond Global's patented process is fundamentally different — it chemically crosslinks the polymer surface, achieving permanent bonds on materials that adhesives cannot grip, including HDPE, PTFE, Delrin, and polypropylene.

To repair a hole in a poly tank, Tech-Bond Global recommends using the Tech Patch and Tech Wrap Kits or the Professional Kit with Filler component. First, prepare the surface using Poly Prep, apply the appropriate bonding agent and filler to fill the void, then accelerate the cure. For larger structural damage, the Tech Patch Repair System (TPRS) provides reinforced patch coverage in widths up to 12 inches.

Tech-Bond Global offers three viscosity options: SI Blue (thin-medium, standard general-purpose use), SI Black (thicker formula for precision control and overhead applications), and SI Green (ultra-thin, specifically engineered for hairline crack repair). Choose SI Green for fine surface cracks, SI Black for gap filling requiring controlled flow, and SI Blue for most standard bonding and repair tasks.

Yes. Tech-Bond Global offers purpose-built Professional Kits and Industry Kits designed for engineers, maintenance technicians, and industrial professionals. These include complete surface preparation systems with Poly Prep, Activator/Accelerator, Filler, and Debonder. The kits are used across mining, energy, marine, solar, agricultural, and manufacturing environments, and are validated through partnership with IIT (ISM) Dhanbad.

All Tech-Bond SI Bonding Agent kits should be stored in a refrigerator to achieve the longest possible shelf life. Before use, bring the product back to room temperature to ensure optimal viscosity and bonding performance. Proper cold storage preserves the chemistry of the bonding agent and prevents premature curing or degradation between uses.
