Bond, don’t glue silicone rubber

Glue silicone rubber”  No, “bond” silicone rubber.

Conventional wisdom is that you can’t glue silicone rubber.  At one time in our history, conventional wisdom told us the world was flat.  Both sentences belong in the dumpster … with one small caveat.  You have to add chemistry and physics to be able to “bond” not glue silicone rubber,    is almost impossible!   However you can bond silicone rubber to itself and to any other substrate.  With the Bonding Poly Process (patent pending) you can bond silicone rubber to itself or to any other substrate quickly, easily and permanently.

Fluorosilicone rubber
Fluorosilicone is one of the most chemically resistant polymers.

When you try to  glue any of the three types of silicone rubber, there is limited flexibility.  With all grades of silicone the bonds created via the Bonding Poly Process (patent pending) are flexible.  OK!  OK!  Wherever and wherever we state that we can bond silicone rubber, the reaction is skepticism.   You skeptics are the reason why we have a money-back guarantee.  If any of our products or kits do not meet your performance expectations, we will refund your purchase price.  Simply return the item.  So far, after having sold thousands of kits, we have not had to make a refund.

To glue silicone rubber

  1. Use sandpaper to rough the silicone rubber then clean the surface with a soft cloth.
  2. Saturate the silicone rubber with an adhesion promoter for poly’s.
  3. Spray one of the silicone rubber 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 12 – 16.
  7. Warm the bond for s 16 – 18 seconds

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

To glue silicone rubber to metal

  1. Rough the silicone rubber and the metal with a low-grit coarse sand paper.
  2. Saturate the silicone rubber surface with an adhesion promoter designed to work with poly’s.
  3. Spray a solvent based Activator/Accelerator (AA) on either the silicone rubber 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 Poly 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)
  • Heat (the physics part of the process.)

When you create a bond for the first time with this process. the is hard to believe.   The first time we bonded a poly (a polyurethane bumper cover), we didn’t believe the result.  Over the next several months, we repeated the Bonding Poly Process again and again.   Testing was done with every polymer we could find.   Success was 100%.  And even when abused, the bond didn’t fall apart.  We asked, why did it take sixteen years to figure out the process?

When working with silicone rubber, it is extremely important to understand that polymers are very slow curing.  Silicone rubber will take thirty days or more to fully cure.  However, in most cases, the repaired silicone rubber can be put into use immediately.

Watch the video below on bonding silicone rubber.  It is important to note that when you’re bonding flexible material, that the adhesive, when applied, must extend all the way to the edge.  You don’t want a peel to start.

Bonding Polymers

To bond polymers, you need at least a Basic Poly Kit.  Our Basic Poly Kit (shown below) includes;

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

Our instruction sheet is easy to understand.

Finally, a comment from one of our Basic Poly Kit users.

Dear Don…no worries…

I’d like to order some more…this stuff is the bomb and has worked perfectly on my slippery silicone …can’t thank you enough 
Can you hold on that shipment so I can add to it …if not …no problem
