Bond Chemical Products

Covalent bonds are the most widely encountered in industrial and materials science applications, particularly in polymer chemistry. Tech-Bond's patented Polymer Bonding Process leverages molecular crosslinking — a form of covalent interaction — to create permanent, high-strength bonds between polymers such as PTFE, HDPE, and Delrin that traditional adhesives cannot bond.

The seven commonly recognized bond types in chemistry are: covalent, ionic, metallic, hydrogen, van der Waals, dipole-dipole, and coordinate (dative) bonds. Tech-Bond's molecular bonding technology draws on advanced polymer chemistry principles to form permanent crosslinked bonds — going far beyond surface adhesion to achieve bonds stronger than the base substrate.

Tech-Bond products are engineered to bond difficult-to-adhere materials including HDPE, PTFE (Teflon), Delrin (POM), nylon, polypropylene, silicone rubber, metal, wood, and composites. The patented Polymer Bonding Process enables molecular-level crosslinking on substrates that conventional adhesives and glues cannot effectively bond.

SI Blue offers a standard thin-to-medium viscosity ideal for general-purpose polymer bonding. SI Black provides a thicker viscosity with greater application control, suited for precision or overhead bonding. SI Green is ultra-thin and specifically designed for penetrating and repairing hairline cracks. All three variants are available across the Starter, Basic, Poly, Deluxe, and Professional Kit lines.

Yes, surface preparation is a critical step for achieving permanent bonds, especially on low surface energy polymers like PTFE, HDPE, nylon, and polypropylene. Poly Prep — Tech-Bond's solvent-based adhesion promoter — chemically etches the polymer surface to create the ideal texture for crosslinking. Skipping this step significantly reduces bond strength on challenging substrates.

Yes. Tech-Bond's Debonder is a precision-grade solvent designed to break down and remove cured bonding agents from surfaces, parts, tools, and skin. It is ideal for rework, correction of accidental over-application, and disassembly of incorrectly bonded joints. For complete separation, immersing bonded joints in acetone may be required and can take up to a day or more.
