According to Silicones: Chemistry and Corrosion, “Single part silicone sealers generally contain a cross-linking catalyst (such as a tin compound) that is activated upon exposure to moisture in the air.” When acetic acid is released, it attacks and corrodes metals such as copper, zinc, brass, and galvanized steel.

Beside this, does silicone sealant corrode copper?
Silicone. Silicone is the type of caulking that seals metal surfaces, such as copper. One hundred percent silicone caulking works well for most applications involving copper, including those that sustain high heat, such as flashing around chimney outlets.
Also, does silicone stick to aluminum? Silicone sticks to aluminum just fine. All my DIY LEDs so far have plastic siliconed to aluminum. With the right hand style setup if you put plugs of silicone through the holes into the glass even if it doesn't stick to the metal, the mushroom head that oozes out will hold it in place.
Keeping this in consideration, does silicone caulk adhere to metal?
Many commercial caulks adhere well to metal surfaces. Silicone caulk made for metal offers ease of application, permanent flexibility and durability to freezing and heat; it works well to effectively seal smaller gaps.
Is RTV silicone corrosive?
Acetoxy Cure and Neutral Cure Silicones. The most commonly used RTV silicones are acetoxy cure silicone and neutral cure (oxime) silicone. Oxime, or neutral cure silicone, on the other hand, is non-corrosive and has excellent oil and temperature resistant properties.
Related Question AnswersDoes silicone corrode metal?
Silicone itself doesn't cause rust, but it traps any moisture that gets under it. And rust absorbs moisture like a sponge and perpetuates itself. If you silicone over one side of rusted sheet metal, or a blind seam, you've made matters worse.Will silicone stick to rust?
The acid curing silicone is corrosive and would etch into the paint and ultimately cause rust. This is usually designed for use on glass. The neutral cure silicone is non-corrosive and I assume will not etch into the paint surface and should not cause rust. This is the type of silicone used for metal roofing etc.Does silicone eat paint?
Silicone oil is used as a filling agent or a spreading agent with waxes. While silicone oil may not be harmful to the paint if it get under the paint and into fiberglass it can cause damage.How do you seal outside pipes?

Different surfaces such as glass, wood, metal and plastic do possess different adhesion properties i.e. good or bad or somewhere in between. This means silicone does not interface directly with wood or metal or any other material, instead it interfaces with the PSA itself.How do you make silicone stick to metal?
To glue silicone rubber to metal- Rough the silicone rubber and the metal with a low-grit coarse sand paper.
- Saturate the silicone rubber surface with an adhesion promoter designed to work with poly's.
- Spray a solvent based Activator/Accelerator (AA) on either the silicone rubber or metal.
Will silicone stick to galvanized metal?
Neutral-cure silicones are used successfully in metal fabrication projects. Acid-cure silicones, on the other hand, can have a corrosive reaction with galvanized metals. On the other hand, acid-cure silicone can etch the surface of aluminum and increase adhesion.Can you superglue silicone?
Specifically, silicone glue or or silicone caulk will work best, as these have goodies added to increase tack, plus they're made of a very hardy silicone which can cure in contact with any type of surface.
