Adhesive Repair Kits for Concrete Cracks

SI Green (ultra-thin) is specifically designed for hairline crack repair where the adhesive must penetrate fine fractures. SI Blue (thin-medium/standard) suits general bonding and maintenance. SI Black (thick) provides maximum control for precision applications, overhead bonding, or areas requiring a slower, more deliberate application pace.

Yes. The Deluxe and Professional Kits are designed explicitly for technicians, engineers, and maintenance professionals. They include a full bonding system — Poly Prep, bonding agent, activator/accelerator, filler, and debonder — trusted for field and shop use across mining, energy, infrastructure, and industrial manufacturing environments.

Tech-Bond kits bond a broad range of materials including PTFE (Teflon), HDPE, Delrin (POM), rubber, silicone, nylon, polypropylene, metal, and composites. The patented Polymer Bonding Process enables molecular-level bonding on surfaces previously considered unbondable, making these kits uniquely versatile compared to conventional adhesives.

Yes. Surface preparation is a critical first step. Poly Prep, the adhesion promoter included in most kits, etches low-surface-energy polymer surfaces to create the right texture for a strong, permanent bond. Skipping this step on difficult substrates like PTFE or HDPE significantly reduces bond strength and long-term durability.

All Tech-Bond bonding agents and kit components offer an extended shelf life when stored in a refrigerator. Before use, components should be brought back to room temperature. Proper cold storage maintains the chemical integrity of the bonding agent and activator, maximizing usability over time for both occasional and high-frequency repair users.
