Polymer Repair Compounds

SI Blue is a standard thin-to-medium viscosity formula suitable for general-purpose bonding. SI Black is a thicker viscosity that provides greater control for precision or overhead applications. SI Green is an ultra-thin formula specifically designed to wick into and repair hairline cracks. Selecting the correct viscosity is critical for achieving the strongest, most reliable bond for your specific repair task.

Yes, for low surface energy polymers such as HDPE, PTFE, nylon, and polypropylene, Poly Prep is an essential pre-treatment step. This solvent-based adhesion promoter etches the polymer surface, creating the texture necessary for the bonding agent to form a strong, permanent connection. Skipping this step on difficult substrates will significantly reduce bond strength and durability.

Yes. The Tech Patch and Tech Wrap Kits, part of the Tech Patch Repair System (TPRS), are specifically designed for field deployment on metal pipes, metal tanks, and PVC pipes. Available in widths from 2 to 12 inches, these kits require no special equipment and have been successfully used in industrial and infrastructure settings, including repair of a 78-inch HDPE pipe for Borouge in Abu Dhabi.

Tech-Bond Global's Debonder is a precision-grade solvent that dissolves and removes cured bonding agents from surfaces, parts, tools, and skin. It is suitable for cleanup of adhesive drips, rework of incorrectly bonded joints, and disassembly tasks. For complete joint separation, immersing the bonded area in acetone may be required. Always use the Debonder in a well-ventilated area and test on sensitive finishes before full application.

All SI Bonding Agent kits and related components should be stored in a refrigerator to achieve the longest possible shelf life. Before use, allow the product to return to room temperature. Poly Prep should be stored in a cool, dry place per solvent-based product safety guidelines. Proper storage ensures consistent performance and prevents premature curing or degradation of active ingredients.

The Professional Kit and Deluxe Kit are both designed for professional technicians and engineers requiring a comprehensive repair solution. Both include a bonding agent (in your choice of SI Blue, SI Black, or SI Green), Poly Prep surface preparation, Activator/Accelerator, and Filler. The Professional Kit additionally includes a Debonder for full lifecycle bonding control. Industry-specific kits are also available for Taxidermy, Prep Room, and Solar applications.
