Bonding Silicone To Stainless Steel

Figuring out what type of glue to use to adhere one material to another is important.

Bonding silicone to stainless steel. A convenient alternative to welding it s the strongest solution for bonding most metals including iron steel aluminum brass copper and pewter. Saturate the silicone rubber surface with an adhesion promoter designed to work with poly s. Metal to glass grades include. Ptfe adhesive bonding ptfe with industrial adhesive.

Since there are endless combinations of things that could be adhered together there needs to be some sort of guide. For example we needed to glue a piece of wood to metal that was going to hold over 100 pounds. Or see our new stainless steel bonding grades here. 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.

Uv curable adhesives bond well to stainless steel providing the second substrate permits uv light to pass through. Another option for gluing metal is epoxy. This is an advantage adhesives also. 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.

As with silicone other surfaces can be difficult to adhere to look at the list in the low surface energy. Stainless steel is easy to bond but may need to be cleaned to remove dirt dust fingerprints and machine oil. 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. Spray a solvent based activator accelerator aa on either the silicone rubber or metal.

For highest bond strength contact permabond for a specialty stainless steel bonding adhesives. Steel surfaces are typically coated before or after bonding to prevent corrosion either with zinc galvanized steel or some type of paint. Steel steel is an alloy of iron with a small amount of carbon to increase strength. 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.

3m silicone adhesive transfer tapes and double coated tapes bond silicone rubbers and foams to themselves and to other substrates on contact without priming. To glue silicone rubber to metal rough the silicone rubber and the metal with a low grit coarse sand paper. Examples range from the bonding of metal housings and turbine blades in aircraft engines and components to sealing pacemakers. The most common application would be that of non stick frying pan coating.

Use an etching primer on bare metal or a bonding primer on previously. 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. This stainless steel bonding allows the original strength and aesthetic appeal of the part to remain.
