Materials Once Considered Impossible to Bond. Industrial Assets Once Destined for Replacement.
That was then. This is now
The world cannot reliably bond HDPE, Polypropylene, PTFE, silicone rubber, EPDM, polyethylene, FVMQ, nylon, or really any polymer. Tech-Bond has successfully bonding these materails for ten years with our patented Polymer Bonding Process. If you need to bond or repair a polymer, click on the gray button below.
Examples of how well the Polymer Bonding Process and the Tech Patch Repair System (TPRS™) work.
Test Results #1: The First Example Features the Impossible to Bond HDPE.
The testing was done by the Borouge Company of Abu Dhabi. The pictures to the right come from that testing. What was the problem? Answer: The 78 inch diameter HDPE pipe that supplies water to cool their nuclear facility and takes that water out was cracking. Without the water for cooling, the nuclear reactor could blow. It was a literal crisis. If the pipes failed, a nuclear incident would be the likely outcome.
Borouge had to do a worldwide search to find us. Borouge did not want to have the expense of installing new pipe. The first repair system they found, the repair fell apart when it was put into water. HDPE pipe is that difficult to repair. We had just developed the Poly Fill as a repair material. The white line that you see in the picture on the right is the Poly Fill. The Poly Fill was developed to fill cracks or to repair damaged areas, like the pitting that occurs on a steel pipe.
Testing was done under the guidelines of ISO 1167 and ISO 13487
We decided to not only fill the crack that were put into the PE 100, 4″ diameter HDPE pipe, but to also put a coating via manually 3D printing a poly sheet onto the outside of the SDR 11 HDPE pipe. We shipped the pipes back to Borouge for testing. SDR 11, PE 100 4″ diameter HDPE pipe is rated at under 300 psi. The engineers at Borouge were anxious to put our samples to the test.
When ISO 1167 and ISO 13487 begins at a low level so they started testing at around 300 psi. When there was not a failure at the tested psi, the engineers increased the pressure and ran the test again … and again … and again … and again. Failure did not occur rntil1800 psi and it took over 100 hours for the pipe to burst. Obviously an unexpected result. And if you look closely at the picure, you can see the pipe burst, not the repair, and when it burst the poly sheet peeled off.
Testing was initially done at 20°C (about 68°F) and then at 80°C (176°F). Same results. The pipes burst at 800 psi after 100 hours rs. Those results match the numbers generated at 20 °C. The Borouge engineers were shocked at the results. However, in all the testing done since then, those results for TPRS™ are typical.
Test Result #2: 1,000 Hours of Salt Spray Exposure — No Delamination, No Rust Beneath the Wrap, No Blistering, No Creeping
Steel, ductile iron, and cast iron are among the most widely used pipe materials in municipal water, wastewater, and industrial systems. Ductile iron remains important in new installations, while aging cast iron infrastructure continues to present significant maintenance challenges.
In independent ASTM B117 salt spray testing conducted by MEi, steel specimens protected with Tech-Bond’s bonded wrap system endured 1,000 hours of accelerated salt spray exposure without delamination, blistering, creeping, or corrosion beneath the protected areas. Why? There was no moisture intrusion
The implications are enormous. Without moisture intrusion, rust just doesn’t happen. Think about that for a moment. No rust. How much will that save youe organization this year? Over the next five years? Over the next ten years?
What happened to the rust? Rust doesn't just disappear!
Chemistry happened. Molecular Integration (MI) happened.
Why Molecular Integration Matters in Corrosion Protection. The laws of Chemistry do not change. Epoxies use mechanical adhesion to connect the surfaces. The result is two units. As the graphic illustrates, covalent bonds generated via Molecular Intragration creates a unified structure.
Why Molecular Integration™ Matters in Corrosion Protection
Moisture intrusion is one of the principal causes of deterioration beneath conventional protective coatings and repair systems. Tech-Bond’s Molecular Integration™ technology is designed to establish intimate, durable bonding between the protective material and the underlying substrate, minimizing the interfacial pathways through which moisture and corrosive contaminants can penetrate.
In independent ASTM B117 salt spray testing, steel specimens protected by Tech-Bond’s bonded wrap system endured 1,000 hours of exposure without observed delamination, blistering, creeping, or corrosion beneath the protected areas. These results provide compelling evidence of the system’s protective performance on the tested steel specimens.
The broader implications extend to ductile iron, cast iron, and other pipe substrates, where equivalent performance remains to be demonstrated through substrate-specific testing.
Our Technology, the Polymer Bonding Process generates Molecular Integration between surface layers.
Our proprietary product, the Tech Patch Repair System (TPRS™), uses Molecular Integration to bond each layer to either the pipe/tank substrate or to another layer of TPRS™.
PTFE-coated E-glass fabric combines the exceptional tensile strength and dimensional stability of E-glass fibers with the chemical resistance, moisture resistance, and low-friction properties of PTFE.
When integrated with Tech-Bond’s Polymer Bonding Process and Molecular Integration™ technology, this high-performance material becomes a critical component of TPRS™, providing a strong, durable, corrosion-resistant repair system designed to withstand demanding industrial environments.

With the Polymer Bonding Process and Molecular Integration, Materials Once Considered Impossible to Bond. Industrial Assets Once Destined for Replacement Can Now Be Bonded or Restored.
Our patented Polymer Bonding Process™ will bond ANY polymer to itself, to other polymers, and to almost any other substrate.
A bold statement? Absolutely. But one backed by ten years of real-world applications, customer experience, and independent laboratory testing across international markets.
Together, our breakthrough Polymer Bonding Process™ and groundbreaking Tech Patch Repair System (TPRS™) are changing what is possible in industrial bonding and repair.
Materials once considered impossible to bond. Pipes and tanks once destined for replacement. Tech-Bond changes both.
The world also cannot repair HDPE tank and pipes, steel tanks and pipes, etc. The Tech Patch Repair System will repair any type of commonly used pipe or tank substrate and do it quickly, easily and permanently. Tech-Bond has been doing both of the above for the last ten years. If you need to repair an HDPE or other plastic pipe or tank, press on the blue button below.
The world does have repairs systems that repair metal pipes and tanks. These systems usually require numerous wraps to be effective. If you want a repair that will seal your metal or tank with one layer of patch, press the gold button below.
What Real Tech-Bond Customers are saying:
Most importantly, the world still lacks a reliable method for permanently repairing damaged HDPE pipe. Conventional composite wraps may reinforce or contain the damaged area, but they often function like a bandage: they sit on top of the pipe without creating an integrated connection to the substrate or mechanically arresting the original damage. Cracks may continue to propagate, movement may continue beneath the wrap, and moisture, creep and repeated loading can eventually contribute to delamination or repair failure. Steel pipe presents its own challenges, especially in demanding mining, marine, water and wastewater environments where corrosion, abrasion, vibration, pressure and chemical exposure compound the problem.
Tech-Bond changes that equation. The Tech-Patch Repair System (TPRS™) begins by arresting existing cracks and then engineers the repair around the substrate, damage and operating environment. The patented Polymer Bonding Process creates covalent bonds and Molecular Integration™ across the prepared interfae. Instead of remaining a separate layer sitting on top of the damage, the Tech Patch or Tech Wrap becomes integrated with the HDPE, steel, copper, cast iron or other substrate. The completed repair transfers loads, resists delamination and limits further damage—restoring structural continuity and extending the service life of the pipe or tank.

Polymer Bonding Process
Breakthrough Technology Number 1
The Polymer Bonding Process™ is a complete engineered method for permanently bonding polymers. Polymers traditionally cannot reliably be joined. HDPE, LDPE, polypropylene, PTFE, UHMWPE, TPU and other low-surface-energy plastics resist being glued. Instead of asking an adhesive to stick to an untreated surface, the Process engineers the entire interface through controlled surface preparation, chemical treatment, bonding-agent application, pressure and precisely managed heat. These coordinated steps enable molecular bonds and cross-links to extend through the interface, creating an integrated structural connection rather than a temporary surface attachment. The result is a strong, durable bond capable of withstanding flexing, vibration, temperature changes and demanding service conditions across all applications.

Molecular Integration™ (MI™)
Molecular Integration™ describes what occurs when the Tech-Bond system is applied to one or more non-polymer surfaces. Metals, ceramics, glass, stone and other rigid substrates behave differently from polymers and require a different interface-engineering approach. After thorough cleaning and mechanical conditioning, a catalyst activates the prepared surface and accelerates the bonding reaction. The Bonding Agent is applied in a controlled quantity, the surfaces are brought together under pressure, and carefully managed heat supports material conformance. The result is not simply an adhesive film sitting between two materials. Molecular Integration™ creates a unified, engineered interface designed to resist moisture penetration, creep, delamination, vibration and thermal cycling. This allows non-polymer materials to be permanently joined to themselves, to other non-polymers or to compatible polymer systems.

Proof of Performance and Validation for Tech-Bond and the Tech Patch Repair System (TPRS™)
Testing Results
Independent testing has not produced one isolated success. Testing has revealed a consistent pattern of superior performance across different materials, environments and failure modes. A repaired HDPE pipe withstood 1,800 PSI for more than 100 hours. ASTM B117 salt-spray exposure reached 1,000 hours with no delamination, rust or creep. Thermal and accelerated-aging tests left the bonded interfaces intact—even when the HDPE itself bent. During tribology testing, E-glass fibers tore before the interface failed. The complete Polymer Bonding Process™ increased the observed PTFE-to-steel temperature capability from approximately 220°F to approximately 330°F. In aramid-fiber testing, the Tech-Bond system carried approximately 1,950 newtons compared with a 1,200–1,300-newton baseline, while the fiber elongated into individual filaments without premature interface failure. Across the board, the pattern has been the same: the surrounding material reaches its performance limit before the engineered interface fails. These are not merely stronger joins; they are evidence that properly engineered interfaces can change how materials perform.
