Silicone Rubber Solvent

Use this rubber chemical resistance chart to make sure that the elastomer or o ring seal you choose will be compatible with the particular environment.

Silicone rubber solvent.

This solvent has been specifically developed to digest silicone deposits through depolymerisation and dissolution leaving a silicone free surface. Warm both surfaces with a hair dryer or heat gun. Silicone rubber also has excellent resistance to solvents and other chemicals. Liquid used to remove cured silicone from surfaces equipment and manufacturing units.

The cross linked bonds of silicone caulk are too strong to dissolve in this way but some chemicals can cleave the siloxane bonds and break the long polymer chains into smaller molecules. Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. Wipe material with a clean rag or scrape from surface with permatex saferscraper. A silicone solvent actually digests silicone when a solvent dissolves a solute it breaks the solute into atoms or molecules that can disperse in the solvent.

Silicone caulk lasts for many years but it does wear out and when it does you need to remove it before you can apply fresh caulk. Spread liberally on surface and let stand for several minutes to soften gasket material. Saturate the silicone rubber with an adhesion promoter for poly s. Combinations of solvent and silicone emulsifier may also be used where the silicone matrix swells from absorbing solvent and allows easier access of silicone emulsifying solutions into silicone.

Remove heavy silicone residue using permatex saferscraper. For example a silicone rubber gasket exposed to certain solvents will swell to form a tighter seal. Welcome to our rubber chemical resistance chart. Once these solvents are absorbed into the silicone rubber regardless of the geometry the silicone rubber will expand in size and once it has expanded enough to allow the silicone to easily accept the fitting or rigid part the solvent evaporates and the silicone rubber returns to its original size.

After the solvent has completely evaporated the silicone rubber will return to its original physical properties. Spray one of the silicone rubber surfaces with a solvent based activator accelerator aa. Silicone rubber has outstanding resistance to oil at high temperatures. Allow longer contact time for thick layers.

Among common organic rubbers nitrile rubber and chloroprene rubber have somewhat higher oil resistance at temperatures below 100 c but at higher temperatures silicone rubber is superior. When heat is used to accelerate the chemical breakdown of the silicone properties such as boiling point flash point and heat sensitivity of active. To glue silicone rubber. Warm to very warm but not hot.

Anyone who has ever done this knows that some household solvents soften silicone caulk but none dissolves it a common removal strategy is to soften the caulk with a generous amount of a softening agent and then cut it off with a knife or pull it off with pliers. Use sandpaper to rough the silicone rubber then clean the surface with a soft cloth.
