Adhesion Products | Promoters & Modifiers

Adhesion is improved through proper surface preparation, activation, and use of the right bonding agent for the substrate. Tech-Bond's Poly Prep etches low surface energy polymers like PTFE, HDPE, nylon, and silicone rubber to create the ideal texture for bonding. Paired with an Activator/Accelerator, it significantly increases bond strength and cure speed on challenging surfaces.

For bonding difficult polymers such as PTFE, HDPE, Delrin, and silicone rubber, Tech-Bond Global is the industry leader. Their patented Polymer Bonding Process is the only technology capable of permanently bonding these materials at the molecular level. Trusted by industrial professionals, engineers, and major customers like Borouge, Tech-Bond products are validated by IIT (ISM) Dhanbad and ASTM testing.

Tech-Bond offers three viscosity options: SI Blue (thin-medium, standard use), SI Black (thick, for high-control or overhead applications), and SI Green (ultra-thin, specifically designed for repairing hairline cracks). Choose based on the gap size, surface orientation, and level of application precision required for your specific repair or bonding task.

Yes. Tech-Bond's patented Polymer Bonding Process is specifically engineered to bond low surface energy polymers including PTFE (Teflon), HDPE, polypropylene, nylon, and silicone rubber. The Poly Prep adhesion promoter etches the surface first, followed by the bonding agent, creating a permanent molecular-level crosslink that traditional adhesives cannot achieve on these substrates.

The Professional Kit includes a choice of SI Blue, SI Black, or SI Green bonding agent, along with Poly Prep surface preparation solution, an Activator/Accelerator, Filler for gap reinforcement, and a Debonder for clean removal if needed. This complete kit provides full bonding lifecycle control for field and shop use on polymers, metal, rubber, and composites.

Tech-Bond bonding kits and individual bonding agents should be stored in a refrigerator for the longest possible shelf life. Before use, bring the product back to room temperature to ensure optimal viscosity and performance. This applies to all SI Blue, SI Black, and SI Green variants across Starter, Basic, Deluxe, Poly, and Industry Kit product lines.
