How can I repair a tear in a silicone wall?
I was bonding silicone to plastic, but I'm sure it will repair a tear. You'll need two products: 3M AC79 primer and PR100 adhesive. Apply the AC79 first, and then apply the PR100 on top of that. I think that should work well for you if you haven't already resolved this.

Will silicone stick to cured silicone?
It is recommended that any old silicone is removed. While new, freshly applied silicone can be applied & will bond to old silicone – the bond isn't as strong as if it were applied to a clean surface.
Will boiling water melt silicone?
No, silicone does not melt in boiling water. Silicone has its high heat bearing capacity and does not easily melt. It is heat resistant up to 250-400 degrees Celcius.
What happens when you heat silicone?
While most plastics will begin to melt at high temperatures, silicone does not have a melting point and remains solid until combustion occurs. At high temperatures (200-450oC), silicone rubber will slowly lose its mechanical properties over time, becoming brittle.

What is the best glue for rubber?
Cyanoacrylate adhesiveCyanoacrylate adhesive, commonly known as super glue, is generally the best adhesive for rubber bonding. You only need a very small amount and the bond becomes very strong and rigid almost instantly. If the joint falls apart after curing, it may be due to the type of rubber you are using.
What to use for tear ins?
If the tear in isn't in an area that has to stretch in use, I'd suggest also adhering on a layer of nylon or fiberglass mesh as reinforcement, since the repair is likely to be weaker than the original part, which has already failed.

What is platinum cured silicone?
Two component platinum cured silicone rubber or platinum catalyzed silicone rubber or addition cure is extremely flexible, as well as strong. This flexibility and strength, combined with its library life, make it an ideal candidate for molecular bonding. More than applying a thick and clumsy sticky glue paste, a molecular bond is as it sounds. It forms a covalent bond between the two surfaces. With both the expensive cost of platinum and the precision required for accurate molds, bonding is really more of a must than a candidate. Paste epoxies that work by being sticky, simply do not provide adequate working time.#N#The molecular Process allows up to two minutes to perfectly align your platinum silicone, as long as you spray the Activator from the outside once bonded. The other bonding method calls for spraying the Activator on the opposite surface, but the bond with this method is almost immediate and does not provide ample working time. Platinum-cured silicone is often used in the food, beverage and medical sectors. Our molecular bonding system is food and dishwasher safe once dry.#N#Working with freshly minted platinum-cured silicone rubber is especially difficult. Chemical reactions are sill going on within freshly minted silicone rubber. Those reactions interfere with the chemical reactions critical to the Process . What is needed to offset the newness issue, is time. Once you firmly press the two pieces of freshly minted, platinum-cured silicone rubber together for the fifteen seconds necessitated by the Process, you need to give the result time.#N#Give the new/repaired piece a minimum of twenty-four hours to cure. Then you can put the piece back into use. More mature platinum-cured silicone rubber is easier to bond, but we still recommend the wait for all platinum-cured silicone rubbers. Platinum cured silicone is the most transparent silicone. Our surface insensitive adhesive and bonding tools dry clear. The sheer and tensile strength of platinum silicone, necessitate the need for a strong bond. Be sure to apply firm pressure and allow for the curing time.
Why is silicone rubber so hard to glue?
From trial and error, we have learned that, with elastomers, pressure is needed to create a bond to any surface. Greater pressure than with polymers like nylon, HDPE, polypropylene, etc. The key to bonding any type of silicone is applying extra firm pressure for fifteen seconds, when the two surfaces are brought together. When this technique is used in conjunction with the Process, the silicone will be permanently, covalently bonded.
What is methyl phenyl silicone?
Methyl phenyl silicone is a specialty silicone product with increased phenyl concentration. The addition of phenyl in replace of methyl, offers specific enhancements not present in standard silicone rubber. These improved characteristics include oxidation resistance, thermal stability, shear strength, visual clarity, radiation resistance, severe temperature resistance, severe pressure resistance, electric insulation and imperviousness to nearly all chemicals. Methyl phenyl silicones are the silicones used to produce permanent, non-stick coatings in pots and pans, that can withstand extremely high heat.#N#It is important to note all of these extraordinary properties when attempting to ‘ glue ‘ or bond methyl phenyl silicones. Our conductive bonding agent and subsequent bonding poly process can withstand a pressure, shear and tensile strength in the range of 2500 psi and below. We recommend avoiding bonding application where the temperature would rise above 240 degrees Fahrenheit. Our surface insensitive adhesive bonds are also impervious to nearly all chemicals. Most ‘super’ glues and epoxies are not able to withstand the specific extremes methyl phenyl silicones were designed for. Below is a picture of methyl phenyl silicone resin.
What is RTV silicone?
RTV Silicone Types. RTV silicone molds are distinguished by the type of curing process they employ. The most common of these are platinum cured silicones (addition cure), peroxide cured silicones (free radical cure) and tin cured silicones (condensation cure). It is possible to bond all silicone mold types.
What is platinum silicone used for?
Platinum-cured silicone is often used in the food, beverage and medical sectors.
How does silicone bond?
Our Process uses the laws of chemistry and the principles of Physics to create bonds. With elastomers, pressure effectively increases the surface area area available to bond. With the added pressure, the Process will bond silicone to itself, to any other polymer and/or to any other substrate quickly, easily and permanently. The steps of the Process are outlined later down the page. There is one type of silicone, platinum-cured silicone rubber, that requires extra steps to generate the results that you want. The details of the special treatment needed for platinum-cured silicone are at the bottom of this page.
How long does it take for silicone to bond?
The key to bonding any type of silicone is applying extra firm pressure for fifteen seconds, when the two surfaces are brought together. When this technique is used in conjunction with the Process, the silicone will be permanently, covalently bonded.
