Waterproof Crack Repair Compounds & Sealers

Yes. Tech-Bond Global's repair systems are engineered to create permanent, waterproof molecular-level bonds. The Tech Patch Repair System (TPRS) has been validated in wet, pressurized pipeline environments, including the successful repair of a 78-inch HDPE pipe. Kits are compatible with metal, PVC, HDPE, and PTFE — all common in fluid-handling and containment systems.

Tech-Bond Global products are designed for a wide range of substrates including HDPE, PTFE (Teflon), Delrin (POM), silicone rubber, nylon, polypropylene, metal pipes and tanks, PVC, wood, and composites. The patented Polymer Bonding Process enables bonding of materials historically considered unbondable, making these solutions uniquely versatile for industrial and field applications.

Yes, for polymer substrates surface preparation is critical. Poly Prep — an adhesion promoter — etches the surface of low surface energy plastics like HDPE, PTFE, nylon, and polypropylene to create proper texture for a strong bond. This step is included in most kits. For metal and composite surfaces, standard cleaning and degreasing is recommended prior to applying the bonding agent or filler.

Absolutely. Tech-Bond Global's repair systems are specifically designed for fast, field-deployable use without special equipment. The Tech Patch and Wrap Kits and bonding kits can be applied on-site in industrial, infrastructure, and utility environments. No special tools or curing ovens are required, making them ideal for emergency pipe repairs, leak control, and unplanned maintenance situations.

Three viscosity options are available: SI Blue (thin-medium/standard) is ideal for general bonding tasks. SI Black (thick) offers superior control for overhead or precision applications. SI Green (ultra-thin) is engineered specifically for penetrating and repairing hairline cracks. All kits include viscosity selection guidance, and Tech-Bond Global's team is available to provide application-specific recommendations.

Tech-Bond bonding agents have an extended shelf life when stored in a refrigerator. Users should bring the product back to room temperature before use. This refrigerator storage recommendation applies across the SI Blue, SI Black, and SI Green bonding agents in all kit types — Starter, Basic, Poly, Deluxe, and Professional — ensuring product integrity for both infrequent and regular users.
