Bond, don’t glue Polypropylene

Glue Polypropylene?  No, “bond” Polypropylene, with the Bonding Poly Process (patent pending)

Conventional wisdom is that you can’t polypropylene or any other polymers.  With the use of an adhesion promoter and a CA you can get a modest glue join with some nylons.  By adding the power of  chemistry and and the laws of physics you can now “bond” polypropylene  … to itself or to any other substrate.  By using the Bonding Poly Process (patent pending), you can bond polypropylene to polypropylene or to any other substrate quickly, easily and permanently.

Wherever and wherever we state that we can bond polypropylene or any other poly the universal reaction is skepticism.  Skeptics are the reason why we have a money-back guarantee.  If any of our kits do not perform to your expectations, we will refund your purchase price.  Simply return the kit.  So far, after selling thousands of kits, we have not had to make a refund.

Polypropylene is one of the most used polyolefins. An array of car parts made of polypropylene is shown above.

To glue polypropylene

  1. Use sandpaper to rough the polypropylene then clean the surface with a soft cloth.
  2. Saturate the polypropylene with an adhesion promoter for polymers.
  3. Spray one of the polypropylene surfaces with a solvent based Activator/Accelerator (AA).
  4. Warm both surfaces with a hair dryer or heat gun.  Warm to very warm but not hot.
  5. Apply an SI cyanoacrylate to the opposite surface (from where you sprayed the Accelerator).
  6. Firmly press for ten-fifteen seconds.
  7. Warm the bond for s 16 – 18 seconds

As a result of this process, the two polypropylene surfaces will be bonded.  Operational strength is achieved almost immediately.  Full strength will take at least as month. 

To glue polypropylene to metal

  1. Rough the polypropylene and the metal with a low-grit coarse sand paper.
  2. Saturate the polypropylene surface with an adhesion promoter designed to work with poly’s.
  3. Spray a solvent based Activator/Accelerator (AA) on either the polypropylene or metal.
  4. Warm the polypropylene surface with a hair dryer or heat gun.  Warm to very warm, but not hot.
  5. Apply an SI cyanoacrylate to the opposite surface from where the accelerater was sprayed.
  6. Firmly press for ten seconds.
  7. Warm the bond for twenty seconds

as a result of this process, the polypropylene and metal surfaces are bonded.  Operational strength is immediate.  Full strength will take at least as month. 

Bonding Polymer Process (patent pending)

What’s the secret of the Bonding Poly Process?  It’s how we combine

  • a polymer-enhanced, Surface Insensitive Structural Cyanoacrylate  
  • our standard Activator/Accelerator, (the chemistry)
  • the Poly Prep (chemistry again)
  • and heat (the physics part of the process.)

As a result of the Bonding Poly Process, your result is hard to believe.  Our first bond (repairing a polyurethane bumper cover), shocked us.  We didn’t believe the result.  Over the next several months, we repeated the Bonding Poly on every polymer we could find.   Success was 100%.  When the results were tested?  Even when abused, the bonds didn’t fall apart.  Finally, we asked ourselves, why did it take us sixteen years to figure out the process?

When working with polypropylene, nylon, Delrin®, polypropylene or any other poly, it is extremely important to understand that polymers are very slow curing.  Bonds will take thirty days or more to fully cure.  However, in most cases, the item can be put into use immediately.

Watch the video below on bonding Delrin®.  In this case. we bond Delrin® to polypropylene.


Bonding Polymers

To bond polymers, you need one of poly kits.  Our Basic Poly Kit (shown below) includes;

  • an SI Structural Cyanoacrylate,
  • our standard Activator/Accelerator,
  • the  Poly Prep,
  • Finally, a detailed step-by-step instruction sheet.    

Our instruction sheet is easy to understand.
