What do you need to fix, repair, or bond?
Whatever your problem, you have reached the right place.
Tech-Bond's Kits use chemistry to molecularly integrate surfaces to generate permanent repairs on variety of items, from fine china or jewelry to hiking boots, a torn bumper cover, crown molding, or a steel/plastic tank. With Molecular Integration, even those difficult materials, polymers like PTFE, silicone rubber, HDPE, nylon, polypropylene, etc. can be repaired or bonded.
Precision is a critical to Molecular Integration
Unlike traditional glues and epoxies—which rely on mechanical adhesion to hold surfaces together—Molecular Integration works through a controlled chemical reaction that bonds materials at the molecular level. Mechanical adhesion can creep, crack, or fail over time. Molecularly integrated bonds are permanent. Precision is required to generate the necessary chemical reaction.
Pressure, just hand pressure in most cases, is necessary to create a quality bond
For elastomers, like silicone rubber, pressure is absolutely necessary to retail flexibility of the silicone rubber. Firm, controlled pressure increases true surface contact at the microscopic level, displacing air and enabling the elastomer’s compliant structure to conform fully to the bonded surface—resulting in a stronger, flexible, more durable bond.
Flexible bonds that are waterproof will allow you to repair shoes, boots, leather coats, reattach heels, etc.
For flexibility, you need to use the smallest amount of Bonding Agent (Integrator). Generally, epoxies are piled on. In essence, the more the merrier. To use an Integrator, less is better. Finally, you let pressure spread the Integrator. You don’t spread the Integrator, let the pressure spread it.

Tech-Bond Platform
The Tech-Bond Platform is built around a single breakthrough: Molecular Integration. Instead of attaching materials at the surface, the platform enables materials to integrate at the molecular level—eliminating the failure mechanisms that drive repeat repairs. This shift makes permanent repair and renewal possible across materials and environments where conventional methods fail.
The platform brings together the Process, applied repair systems, validation data, and disciplined training into one repeatable framework. Combing the aforementioned produces a result that is not a product or a one-off solution, but a scalable way to restore, protect, and extend the life of critical assets—reliably, consistently, and in the field.
What Is Cross-Linking?
Cross-linking is a chemistry- and physics-driven breakthrough that fundamentally transforms how materials bond. Instead of trying to glue one surface to another, cross-linking forms molecular bridges—true chemical bonds—between the repair material and the underlying substrate.
In every Tech Patch Repair System (TPRS™) application, this reaction takes place on the surface of the pipe or tank. The molecules in our bonding agent and the conditioned substrate interlock to form one continuous structure, eliminating seams, gaps, leaks, and the failure points that defeat glues and epoxies.
The result is a bond stronger than the materials themselves—moisture-proof, fuel-proof, vapor-proof, and permanent for the life of the pipe.
Cross-linking doesn’t stick things together.
It makes them one.
Our patented Polymer Bonding Process (the Process) delivers this chemistry consistently and reliably. With proper surface conditioning, the Process works on almost all substrates.
We openly invite and welcome any challenge to this claim.
HOW CROSS-LINKING IS “A CUT ABOVE”.
• Tribology (Stress) Testing (Steel Pipe):
Independent tests at IIT-ISM showed that even under extreme friction, the bond of our Tech Wrap on steel never failed—only the protective layers above it did.
• ASTM B-117 Salt-Spray Test (Corrosion Resistance):
An accredited US engineering firm exposed bonded TPRS to steel samples to 1,000 hours of continuous salt-spray with no delamination and no rust, an unheard of result.
• ISO 1167 / 13479 Pressure Tests (HDPE Pipe):
Borouge, a globally recognized producer of advanced polymers located in Abu Dhabi, testing proved HDPE pipe repaired with the Tech Patch Repair Sysem withstood five times its rated pressure, emerging stronger and more durable than before. Note: An A A Patch was used in the testing, not a Wrap.
Taken together these tests confirm that:
Tech-Bond’s cross-linked interface doesn’t just restore strength—it creates structural enhancement that lasts for the life of the system – a result, in every case, that the competition cannot match.
The proven capability … and future potential …. of our next-generation technologies.
The enormous potential of our breakthrough technologies can only be fully realized through Engagement, Experience, and Execution.
Engagement allows us to understand real-world needs and determine the best fit for each application.
Experience ensures that what we learn in one field can be transferred to others, multiplying the impact of every success.
Execution matters most—our results have proven that when the Process is used to apply Tech Patches and Wraps correctly, it always works.
We are proud to collaborate with the Indian Institute of Technology, Indian School of Mines (IIT-ISM Dhanbad)—a valued partner—as we jointly establish the Tech-Bond Global Center of Excellence in Dhanbad. This partnership will redefine how public and private sectors work together to accelerate innovation. With such vast potential, we will continue forming partnerships with leading educational and research institutions around the world.

Damn fine product. I’ve used it for years in many applications.
Our Amazon rating is 4.6 including the review below on fixing plastic gas tanks – something that the other products do not do well … or at all.
I am a fan of this stuff – I suspect some of the other reviews may not be using it properly (applying heat) or preparing the surfaces thoroughly, it has worked fantastic for me. I originally ordered to repair a leak in a discontinued Audi fuel tank filler neck, that is made from HDPE. Doing my research that nothing else would work on this I used TechBond, and almost the entire content of the SI advesive with the patch and plussing, and my check engine light for EVAP leaks has been gone for the last 2 years.
Case Study
With this Mini Pach, the shop can repair 24 plastic gas tanke. Average material cost per repair < $15.00 per repair. For plastic gas tanks, the client will save over $ 1,000 by having the tank repaired instead of replacing the tank. In today’s world, often there isn’t a replacement tank available.
But that’s another case study.
Step-by-step Instructions for bonding Polymers
The following instructions will allow you to bond, “cross-link”, PTFE, silicone rubber, HDPE, nylon, polypropylene, Delrin, polycarbonate, EPDM, polyester, polyethylene, to themselves, to other polymers and to almost any other substrate.
Precision is critical. Instructions for bonding polymers are below. Each kit comes with detailed instructions.
- Cross-linking begins with Surface Conditioning, as follows:
- Rough the polymer surfaces to below the sheen.
- Clean surfaces with any cleaner that will not leave a residue. Let dry.
- Saturate the polymer surface(s) with the Poly Prep. Let dry.
- Spray a light mist of the Activator/Accelerator over the entire area of ONE (or the) polymers. It does not matter which surface. Often, the destination surface makes the bonding process easier.
- Take a heat gun or hair dryer and warm the polymer surface(s) to about 117-120° F, (47 – 49° C). Best way to check the termperature is by touch. Warm to very warm, to just below hot.
- Apply the Bonding Agent TO THE OPPOSITE SURFACE FROM WHERE YOU SPRAYED THE ACCELERATOR using small concerntric circles to cover the whole surface.
- Run a bead of the Bonding Agent around the entire perimeter.
- Align the two pieces and firmly press the two pieces together for 15 – 20 seconds.
- Visually inspect.
If you are working with polymers, follow the above steps. For metal, wood, rubber, vinyl, carbon fiber, fiberglass, cermanics, shoes, follow the above steps, but eliminating spraying with the Poly Prep and eliminate using the heat. TECH-BOND also bonds non-polymer substrates.
The primary difference between bonds and glue joins is durability of the bond. However, what you will appreciate most is how quickly, and how efficiently bonds form. YOU WILL SAVE TIME!

- Apply the Bonding Agent to the glass fabric side of the Patch using small concentric circles. Thorough, but not heavy.
- Grab the corners, apply tension, align and press onto the tank or pipe.
- Press down the edges.
- Use the glue sqeegee at an angle to apply pressure from the center out. Squeeze every excess drop of adhesive out from between the tank and the adhesive.
- Take a heat gun or hair dryer and warm the patch to about 118-120° F, (49° C). Best way to check is by touch. Warm to just below hot. When it gets hot. STOP.
- Wait one minute. You want the patch to still be warm. Apply beads of the Bonding Agent onto the top of the patch and around the perimeter.
- Use the glue squeegee to spread the adhesive. Spread the Bonding Agent just once.
- Repeat 10 and 11 twice.
- Visually inspect.

Repaired a crack in a Porsche plastic fuel tank with great results so far. After a failed attempt using a name brand epoxy repair kit, I found a YouTube video on this product that claims a permanent repair. It bonds plastic like a Superglue on steroids.
Our repairs are bonded, bonded not glued, together. Thus, repairs made with Tech-Bond products are completed faster and last longer.
To create bonds, Tech-Bond adds:
1) for polymers, both a low level of heat and a catalyst. In most cases both are needed.
2) for non-polymers, a catalyst is all that is needed to create an exothermic chemical reaction which create the bond between the substrates.
In most cases, a superglue or a CA applied without a catalyst does not perform as well as our Bonding Agent and Catalyst. Here’s why.
Without a catalyst
Monomers can connect on their own, but the process is slow and inconsistent.
They may stay “waiting” for a long time before finding a partner.
Result: weaker or shorter-lived bonds, because the chains don’t grow fully or evenly.
With a catalyst
The catalyst does not create the connection itself — it simply makes it easier for the monomers to connect.
It lowers the energy barrier (activation energy) so the reaction happens faster and more completely.
More monomers find partners, and long, strong polymer chains form almost instantly.
Result: durable, permanent molecular bonds
In short: the catalyst doesn’t “force” monomers to bond — it helps them find and form connections faster, more completely, and with greater strength. From our observations, the biggest difference is that bonds are more durable than glue joins.

First Global Solution:
Tech Patch Repair System
(TPRS)
Whether plastic or metal, leaking infrastructure, whether a pipe or a tank, is a global problem—and one that demands a real solution. After years of research and rigorous testing, we found the world’s best patch material: PTFE-coated E-glass Fabric—incredibly strong, highly durable, and perfectly suited for extreme environments.
The Tech Patch Repair System (TPRS) was born when we fused that breakthrough material with our patented Polymer Bonding Process™. Later, we added Poly Fill, our proprietary filler technology, to complete the system. Together, these three components represent a revolution in pipe and tank repair – delivering unmatched durability, chemical resistance, and ease of use.
And we’re just getting started. Two more global breakthroughs are on the horizon, poised to disrupt industries and drive major cost savings.

Trying to repair broken plastic parts has been a nightmare! Trying to repair torn silicone rubber has also generated headaches.
With the Process, you can now repair:
Broken plastic parts or toys.
torn silicone rubber.
broken tab on a car panel.
These repairs can easily be made. There are several limitations of which you must be aware, as follows;
- Surface area. Tech-Bond’s strength comes from the cross linking that the Process generates with polymer surfaces. Unfortunately, limited surface area translates to limited strength.
You can add surface area, and strength, via several different methods. We are going to shoot a video on ways to strengthenPlease call 877 565 7225 to discuss. - Not all polymers are created equal. For example, plastinum-cured silicone rubber, especially freshly minted plastinum-cured silicone is the most difficult polymer to bond … by far. If you need to bond that version of silicone rubber, please call.

Metal Gas tank
Repair Plastic Gas Tanks
Some plastic gas tank manufacturers are recommending the Tech Patch Repair System to repair damaged plastic gas tanks. It is the one system that works long term. The alternative is to use an epoxy. Epoxy manufacturers, including JB Weld, recommend NOT using their epoxy to repair a plastic gas tank. Your choice.
This video covers how to apply an A Patch on on a poly tank. Our patches work on HDPE tanks, polypropylene tanks, nylon tanks and all other poly tanks.
Repair Metal Gas Tanks
Permanent Metal Gas Tank Repair — Resistant to Gasoline, Diesel, and More
The Tech Patch Repair System also delivers a permanent solution for repairing metal gas tanks, with proven resistance to gasoline, diesel, and other common fuels. Unlike traditional patches that degrade over time, our system chemically bonds the patch to the metal surface, creating a fuel-resistant seal that won’t weaken with vibration, pressure changes, or exposure to harsh chemicals. This is not a temporary fix — it’s a long-term repair you can rely on.
Also repairs galvanized water tank and troughs. The bonding process prevents air and moisture from reaching the pipe or tank surface, i.e., no delamintions.
TPRS in the Mining Industry
Revolutionizing Maintenance in the Mining Industry
Globally—and in India—the mining industry spends nearly 25% of total revenue on maintenance. Two persistent, high-cost issues are failing steel slurry pipes and HDPE water lines.
Tech-Bond solves both issues.
-
Steel Pipes: Cracks appear in months; Tech Wrap adds years of service life with just one or two layers.
-
HDPE Pipes: Clamped joints fail at a 25% rate; our fusion bonding process and wrap system will dramatically reduce failures.
Result: Lower maintenance costs, longer asset life, fewer shutdowns, and greater operational efficiency—adding margin back to the bottom line.
Losing 25-35% or more of your annual revenue to maintenance is not sustainable.
Losing 25% plus of your annual revenue to maintenance isn’t sustainable for the mining industry. Tech-Bond’s pipe repair solutions can help reclaim that lost margin by extending the service life of both steel and HDPE pipes thereby reducing replacement costs and downtime across the board.
Engagement, Experience, Execution – The Foundational Principles of Tech-Bond Global
Engagement
Engagement at Tech-Bond means more than presenting a solution — it means actively working with companies and their personnel to uncover and fully define the root problems they face.
We engage by listening, walking job sites, and having real conversations with the people closest to the problem. Whether it’s frequent failures in HDPE water lines, recurring cracks in steel slurry pipes, or costly tank replacements, our goal is to understand these challenges from the inside out.
Through this process, we help companies recognize how the Polymer Bonding Process and Tech Patch Repair System (TPRS) directly solve their issues — with precision, durability, and long-term cost savings. It’s not a one-size-fits-all pitch; it’s collaboration that results in customized, high-performance bonding solutions that benefit the company, the industry, and its bottom line.
Experience
Experience at Tech-Bond is what turns insight into action. We know that we can’t deliver real solutions until we fully understand the issues—and that understanding comes from both engagement and experience.
It’s our experience that allows us to take what we learn from the field and place it in the right context. We’ve seen the patterns, the failures, and the hidden costs across industries. That depth of knowledge is what enables us to connect the dots and deliver targeted, effective solutions using the Process and TPRS.
And when existing tools aren’t enough, our experience tells us it’s time to innovate—to develop new methods, new tools, and even new products. That’s how we stay ahead. That’s how we solve problems no one else can.
Execution
Execution at Tech-Bond is where everything comes together—and where the difference between success and failure is defined. The principles of molecular bonding are fundamentally different from simply applying an adhesive or epoxy. True execution means every technician must understand and follow the precise steps of the Process, using Tech Patches and Tech Wraps exactly as designed. This isn’t casual application—it’s precision work, and it requires discipline.
That’s why execution begins with training. Through Tech-Bond’s in-depth instruction, technicians don’t just learn the how—they learn the why. They understand what makes molecular bonding work and how to apply it in the field under real-world conditions.
But execution doesn’t stop after installation. It also means continuing to engage with our partners long-term—tracking results, refining techniques, and identifying new problems to solve. Execution at Tech-Bond is about consistency, commitment, and continual improvement—so that every application performs, every time.
