“How to glue Silicone Rubber” is among the most searched terms in the polymer world. That search reveals a widespread misunderstanding because you do not want to glue silicone rubber. Silicone rubber is an elastomer, and gluing any elastomer is a mistake. Elastomers are designed to be flexible and to elongate under stress—glues are not. Glues are rigid; they don’t flex, and they certainly don’t elongate. When you glue silicone rubber, you eliminate its key advantages—its flexibility and its ability to stretch and recover. Silicone rubber doesn’t need to be glued; it needs to be bonded. The only proven technology that bonds silicone rubber, while preserving its unique properties, is the Polymer Bonding Process (Process). The only proven technology that bonds polymers is the Process.
Client Testimonial
If you search our reviews, you’ll see the message below repeated time and again. Here’s another repeat, The only technology that molecularly bonds polymers is the Process.
“Don, you are an excellent instructor on how to use your products. I was skeptical, but you were so positive and reassured me that it will work. YES, your stuff works! The magnet bonded very well to the silicone can lid. When I showed my friend, she was very pleased at the results. Now to get to work and make more of these can covers, and hopefully they will sell. THANK YOU! Chris …”
Give the general public the ability to bond polymer and there will be many small business developed. Hopefully Chris will be successful with her invention. An invition only made possible becuase of the Process.
Step-by-step instructions for glueing thick pieces of silicone rubber.
Trying to get SEO placement demands the use of the term “glueing”. SEO needs to catch up with Technology.
- Rough (abrade) the silicone rubber surface(s) to below the sheen. Rough the opposite surface if not a polymer.
- Remove all dirt, grease and residue from the surface(s).
- Saturate the polymer surface(s) (silicone rubber is a polymer) with the Poly Prep. Let dry.
- Spray one surface with our catalyst, the Activator/Accelerator. Let dry.
- Warm both surfaces with a heat gun or hair dryer to about
- Use a glue squeegee to apply pressure onto the thinner piece. You MUST remove every excess to about 120°F or 49°C.
- Apply the Bonding Ageent using small concentric circles to the opposite surface(s) from where you sprayed the Activator/Accelerator. Then run a bead of the Bonding Agent around the entire perimeter.
- Firmly press the two surfaces together for 20 to 30 seconds.
- An exocthermic chemical reaction should start. You should feel the heat from the reaction. IF YOU DO NOT feel an increase in temperature, apply additional heat.
- Inspect.
- Repair as necessary.

When working with silicone rubber, it is important to learn about the best viscosity of the Bonding Agent to use. Viscosity means how thick the Bonding Agent is and that thickness can make a big difference. Learn about Tech-Bond’s viscosities by clicking the button below.

Since 2016, we have been on a mission. That mission is to convince people that “Yes! You can now bond silicone rubber and the result will meet your needs. Interestingly enough, the more experienced the technician, the more difficult it has been to get accross that point. When the Polymer Bonding Process works to your satisfaction, please share the news.
