Adhesive Bonding Materials and Applications

Tech-Bond products are engineered to bond challenging substrates including PTFE (Teflon), HDPE, Delrin (POM), polypropylene, nylon, silicone rubber, metal, composites, and wood. The SI Bonding Agent system works across polymers, while the Filler component addresses metal and composite gap-filling applications where surface area is insufficient.

SI Blue is a standard thin-medium viscosity suitable for general bonding. SI Black is a thicker formula providing greater control for precision or overhead applications. SI Green is an ultra-thin formula specifically designed for wicking into and repairing hairline cracks. Choosing the correct viscosity ensures optimal bond strength and penetration for your specific repair or fabrication task.

Yes, for low surface energy polymers such as HDPE, PTFE, nylon, and polypropylene, Poly Prep is an essential pre-treatment step. It etches the polymer surface to create the correct texture for a strong, permanent bond. Skipping this step on challenging substrates significantly reduces bond strength and long-term durability.

The Activator/Accelerator acts as a catalyst that accelerates the curing reaction of the SI Bonding Agent, reducing set time and enhancing the final bond strength. It is particularly important in applications requiring fast-cure adhesive systems, such as field repairs, high-throughput manufacturing assembly, or time-sensitive maintenance operations.

Yes. Tech-Bond's Debonder is a precision-grade solvent designed to break down cured bonding agents cleanly without damaging most substrate materials. It is effective for rework, correction of over-application, and disassembly of incorrectly bonded joints. For complete joint separation, immersing the bonded area in acetone over an extended period is recommended.

All Tech-Bond SI Bonding Agent kits and components should be stored in a refrigerator to maximize shelf life. Before use, bring the product back to room temperature. The Filler and Poly Prep should be stored in a cool, dry place. Proper storage prevents premature curing and ensures consistent performance across the full product lifecycle.
