I know that the out-gas can adversely affect some types of foam. What else, and how about the actual silicone caulk?

Shouldn't use it to cover an exposed wound

Come on, seriously? There are about 1 million things it CANNOT be used for. How about asking a mroe direct question, get to the point...

If you're talking about pure silicone, there are very few uses for it. I've seen people do thousands of dollars worth damage to their house with it. One fellow used it to caulk every joint on his wood siding, only to discover that you can't paint it, huge mess.

I use for everything I won't have to paint. Never had a problem.


BTW-use some baby oil or mineral oil on your finger to smooth it out not water.

For failure of the RTV bond or damage due to attack by the release of acetic acid?

There are alternatives (i.e. G.E. Silicone II) that do not release acetic acid.

The latter are NOT safe for the repair/assembly of aquaria.

You may be able to use an elastomeric copolymeric based product marketed under the popular name of Goop.

Huh?

I have a tube in front of me that says "GE Silicone II Kitchen and Bath, 100% silicone sealant."

Oh come on. If you could get your caulk in your mouth, you would do it. Hell, I'd never leave the house.

It always causes problems with paint, it fails frequently and, is not a substitute for proper construction methods. Don't believe what the label tells you. Ask any contractor what they think of using that tube you have in front of you in the kitchen or the bath.

So you're using it to mount an electret cartridge into something that's slightly oversized?

Are you looking to use the RTV's resilency to cut down on microphonics? There's several flexible sealants you can use that will not release caustic vapors when curing. You can also use hot melt adhesive to "tack" in place and follow up with a normal curing epoxy paste such as Belzona e-metal or PC-7. The latter is more readily available to the consumer. Both feature excellent tensile and shear strength and have very low toxicities and will not harm any components applied to.

What are the ideal sealing materials for, say, a shower?

Yes, that's the idea. I do have a hot-glue gun, but does hot glue damp sufficiently?

I can tell you what it's not used for. And when I do, you'll understand why I can never go back to Sea World.
