When you google polypropylene gas tank repair, google gives you a snippet from itstillruns.com that claims that polypropylene gas tanks cannot repaired. That statement is false. That snippet is categorically untrue. Itstillruns.com is just a blog site, paid for by ads all over the place. Anyone can submit a blog page on it and we question Google’s newest search algorithm, if their first returned result is a falsehood. But I digress. The good news is that YES YOU CAN, repair a polypropylene gas tank. First let us run through the reasons that the suggestion on itstillruns.com, are a bad idea.
Why NOT To Follow The Advice Of Itstillruns.com
Their recommendations raise many alarming concerns.
Itstillruns.com says to fix a hole in your polypropylene gas tank, you are to melt the plastic back together. But there are SEVERAL MAJOR PROBLEMS with this. First of all, by stretching the remaining plastic out, you are thinning it. The areas of stretched plastic are going to thin and more accident prone. It will not have the same strength as the rest of the tank. Naturally this weakened area suffers from wall thinning, which could result in catastrophic failure. Furthermore, depending on the size of the area to be repaired, you can drastically change the entire shape of your gas tank, which could lead to obvious function and reinstallation problems. There are yet more hazardous problems, with the novice itstillruns.com blog/ad pop up page, but the severity of the first two, eliminates the need to even mention them.
Our Poly Gas Tank Repair video.
If you need further convincing, that you CAN repair polypropylene gas tanks, with our polypropylene gas tank repair kit, our lifetime guarantee should do the trick. Our Tech-Patches are made of a revolutionary poly material, fluorosilicone, that is impervious to gas and age resistant. Itstillruns.com is wrong about one more key fact when repairing polypropylene gas tanks. While gas will tear through MOST adhesives, there are some that are impervious to gasoline and ours is one of them. Our Surface Insensitive Adhesive is completely impervious to gasoline. It will NOT eat through it. Like our Tech-Patches, it is also age resistant and will not degrade or fall off with time. No matter how large or small your repair area is, the TPRS (Tech-Patch Repair System), will fix it without the need for any structural changes or wall thinning. Our Tech-Patches are fully customizable to fit your repair needs. The bonds created between the Tech-Patch and your polypropylene gas tank are permanent, thanks to our patented Bonding Poly Process (Process).
Commonly Overlooked Polypropylene Gas Tank Repair Obstacles
Instructional videos at the bottom of the page.
There are two obstacles that are not usually considered in the repair of a gas tank. These issues are:
- The first we have already covered and that is gas will eventually eat through most adhesives. Gas, oil, nor any hydrocarbon will not have any effect of our SI Structural Adhesives … ever. We have an ongoing lab test where bonds have been immersed in gasoline for a number of years. Bonds have retained 100% strength.
- Gas tanks, especially plastic gas tanks, expand and contract. Cured adhesives do not expand or contract. When gas tanks expand, cured adhesives crack. Gas then leaks. A repair on any gas tank, but especially plastic gas tanks needs to be able to handle the expansion and/or contraction that comes from changes in temperature. Tech-Patches expand and contract with the substrate.
Tech-Patches are made of one of the chemical and weather resistant polymers made. As discussed above, a patch’s flexibility is a necessity in repairing gas tanks. Items needed for the repair of a plastic gas tank are listed below. At the bottom of the page there is a button that will take you to where you can buy a Tech-Patch Kit.
A Tech-Patch, sized to fit the problem. Patches come in sizes from 2″ x 3″ to 6″ x 24″ and can be cut to fit your problem.
A Poly Kit (or higher) which contains:SI Black, our thicker structural adhesive. Thicker to give you the control needed to apply a Tech-Patch.
Poly Prep, an adhesion promoter for polymers and poly plastics.
An Activator/Accelerator (AA), the AA is critical to the Process.
