Black Plastic Hole Fillers

SI Blue offers a thin-to-medium standard viscosity suited for general-purpose bonding. SI Black provides a thicker, high-control viscosity ideal for gap filling and hole repair where precision placement is critical. SI Green is ultra-thin, designed specifically for penetrating and repairing hairline cracks in plastic and polymer components.

Tech-Bond fillers deliver permanent, high-strength repairs — not temporary patches. The Polymer Bonding Process creates molecular cross-links at the surface, producing bonds that are stronger than the original substrate material. These solutions are engineered for long-term field and industrial use with resistance to chemicals, heat, and pressure.

Tech-Bond Professional and Deluxe Kits are specifically designed for both field and shop deployment. They require no special equipment and can be applied on-site in industrial, mining, energy, marine, and infrastructure environments. The inclusion of Poly Prep surface preparation and an Accelerator ensures reliable results even in challenging field conditions.

Depending on the kit selected, contents include a SI Bonding Agent (Blue, Black, or Green viscosity), Poly Prep surface preparation solution, Activator/Accelerator, Filler for gap and hole reinforcement, and a Debonder for clean removal if needed. Professional Kits include all five components, while Deluxe Kits include the core four components.

Tech-Bond bonding kits should be stored in a refrigerator to achieve the longest possible shelf life. Before use, bring the kit components back to room temperature to ensure proper viscosity and optimal bonding performance. This refrigerated storage recommendation applies across the Professional, Deluxe, and Poly Kit product lines.
