Poly Patch Kits

SI Blue offers a standard thin-medium viscosity suitable for general-purpose polymer bonding. SI Black has a thicker viscosity that provides greater control for precision or overhead applications. SI Green features an ultra-thin viscosity specifically formulated to penetrate and repair hairline cracks where thicker agents cannot reach. All three are available across most kit tiers.

Unlike conventional adhesives that bond surfaces by sticking to the outside, Tech-Bond Global's Poly Patch Kits use a patented Polymer Bonding Process that creates molecular-level crosslinks at the surface. This results in a permanent bond that is stronger than the original material, rather than a surface-only adhesion that can peel, crack, or delaminate under stress.

The Professional Kit ($95.95) is the most comprehensive option for industrial and engineering applications. It includes the SI Bonding Agent, Poly Prep surface preparation solution, Activator/Accelerator, Filler for gap reinforcement, and a Debonder for clean removal. It is trusted by engineers, prototypers, and field technicians for permanent bonding on Delrin, PTFE, HDPE, metal, rubber, and composites.

Yes. The SI Green ultra-thin viscosity bonding agent, available in Starter, Basic, Deluxe, and Professional Kits, is specifically designed for hairline crack repair. Its ultra-low viscosity allows it to flow into and fill microscopic cracks in polymer surfaces, restoring structural integrity without requiring mechanical intervention or surface removal.

All Tech-Bond Global Poly Patch Kits should be stored in a refrigerator when not in use to maximize shelf life and preserve the bonding agent's effectiveness. Before application, the kit components should be brought back to room temperature. This refrigerator-storable formula ensures the product remains ready for use over an extended period.
