Plastic Gas Tank Repair using our PTFE Patch

With our patented Polymer Bonding Process (Process) we bond the PTFE Plus Tech-Patch to the damaged HDPE (plastic) gas tank..

  • The brown step if PTFE (Teflon). With the Process, the PTFE is bonded to the damaged area of the tank.
  • Holding the PTFE is fluorosilicone (FVMQ), another polymer. FVMQ is the polymer of choice for high stress environments in the aerospace, automotive and aviation industries.
  • Our patented Bonding Polymer Process (Process) bonds, bonds not glues, any polymer to itself, to any other polymer and to almost any other substrate. With damaged gas tanks, the Process is permanently bonding PTFE to FVMQ.
  • Polymer to polymer bonds made with the Process are the most durable bonds available.

How to repair a plastic gas tank with a PTFE Plus Tech-Patch.

  • If the problem is a crack, drill small holes at each end of the crack to prevent the crack from expanding. 
  • Make sure the PTFE will extend at least one-half inch beyond the problem on all sides.
  • Abrade the area around the crack/hole.
  • Clean that area.
  • Saturate the area around the crack or hole with the Poly Prep.  Let dry.
  • Spray the Activator/Accelerator on the area.
  • Warm the damaged area of the gas tank and the PTFE Tech-Patch with a heat fun or hair dryer.
    • By temperature: to about 120 degrees F.
    • By touch, just below hot.
  • Apply SI Black using concentric circles to the entire area of the patch EXCEPT for diagonal corners.  Make sure that the adhesive will reach the edges around the entire patch.
  • Grab the diagonal corners, apply tension, and press over the damage area of the gas tank.  Grab will occur in 4 – 8 seconds.  Smooth the patch from the center out with your fingers, pressing down and holding the edges for a few seconds.
  • Use a putty knife to apply pressure on the patch from the center out.  This pressure ensures that there is complete contact between the patch and the tank.
  • Glue down the edges.
  • Visually inspect the patch to make sure that there are no problems.

When can you use the repaired gas tank?

With the chemical reaction needed to form a bond, there is always heat. The PTFE Plus Tech-Patch will get hot. When that heat goes away, the tank can be used.
