PTFE Patch Kits

SI Blue offers a standard thin-to-medium viscosity for general bonding tasks. SI Black is thicker, providing superior control for precision or overhead applications. SI Green is ultra-thin and specially formulated to wick into hairline cracks, making it the ideal choice when the damage is very fine and requires deep penetration for a permanent repair.

The Deluxe Kit and Professional Kit are both designed for technicians. The Professional Kit includes all components — SI Bonding Agent, Poly Prep, Activator/Accelerator, Filler, and Debonder — making it the most comprehensive option for field and shop use. The Deluxe Kit is also an all-in-one solution at a more accessible price point for maintenance teams.

All Tech-Bond Global kits have an extended shelf life when stored in a refrigerator. Before use, bring the kit back to room temperature to ensure optimal performance. Proper cold storage significantly prolongs the usability of the bonding agents, making these kits cost-effective for both regular maintenance crews and emergency repair stockpiles.

Yes. The SI Green ultra-thin bonding agent, included as a viscosity option across multiple kit lines, is specifically designed for hairline crack repair. Its ultra-low viscosity allows it to penetrate very fine cracks and create a permanent molecular bond within the damaged substrate, restoring structural integrity without requiring material removal or replacement.

Yes. The Professional Kit includes a Filler component specifically for gap reinforcement, in addition to the bonding agent, accelerator, and surface prep. A Debonder is also included for clean removal if needed. This makes the Professional Kit ideal for structural repairs where gaps or voids exist alongside surface cracking in polymer assemblies.

Tech-Bond Global PTFE Patch Kits serve a wide range of industries including pipeline and tank maintenance, mining, solar energy, marine, automotive, agricultural equipment, HVAC, plumbing, taxidermy, and funeral services. Industry Kits are also available with configurations tailored specifically for Taxidermy, Prep Room, and Solar industry applications.
