Bonding Silicone To Stainless Steel

Heat vulcanized silicone glue.

Bonding silicone to stainless steel.

Since there are endless combinations of things that could be adhered together there needs to be some sort of guide. Another option for gluing metal is epoxy. Spray a solvent based activator accelerator aa on either the silicone rubber or metal. Metals such as aluminum or stainless steel are high surface energy figure 2 above but once the metal is powder coated you will be bonding to a low surface energy skin.

This is an advantage adhesives also. Titanium and stainless steel are often chosen for their strength durability and proven biocompatibility whereas aluminum can be easily processed through molding casting or machining. Saturate the silicone rubber surface with an adhesion promoter designed to work with poly s. For highest bond strength contact permabond for a specialty stainless steel bonding adhesives.

Uv curable adhesives bond well to stainless steel providing the second substrate permits uv light to pass through. Figuring out what type of glue to use to adhere one material to another is important. The most common application would be that of non stick frying pan coating. Examples range from the bonding of metal housings and turbine blades in aircraft engines and components to sealing pacemakers.

If a customer has an adhesion problem with our silicone silicone engineering first ask is the silicone coming away from the adhesive or is the silicone along with adhesive coming away from the other surface. Stainless steel is easy to bond but may need to be cleaned to remove dirt dust fingerprints and machine oil. Steel steel is an alloy of iron with a small amount of carbon to increase strength. Or see our new stainless steel bonding grades here.

To glue silicone rubber to metal rough the silicone rubber and the metal with a low grit coarse sand paper. 3m silicone adhesive transfer tapes and double coated tapes bond silicone rubbers and foams to themselves and to other substrates on contact without priming.

Steel surfaces are typically coated before or after bonding to prevent corrosion either with zinc galvanized steel or some type of paint.

Ptfe commonly known by the trade name teflon or by the techies amongst us polytetrafluoroethylene is a notoriously difficult material to bond as it is non stick by nature. Metal to glass grades include. This stainless steel bonding allows the original strength and aesthetic appeal of the part to remain. Uv610 uv620 uv625 uv670 and uv7141.

Stainless steel adhesives stainless steel glue stainless steel bonding as with other substrates stainless steel adhesives have an advantage over mechanical fasteners as they function well without requiring the part to be altered. Ptfe adhesive bonding ptfe with industrial adhesive. To apply epoxy on metal you have to first fill a paint sprayer with primer.
