Aquarium silicone sealant comparisons

Has anyone had the opportunity to use and compare the following silicone sealants?
Some better than others? Failures? Recommendations?
  • GE Construction Sealant SCS1200 (may be too soft)
  • GE-012A (GE 1 blue tube. Used to say "safe for aquarium use" years ago).
  • Ge RTV 108
  • GE IS808
  • All Glass (AGA)
  • Permatex 16B
  • CRL 99AS
  • Perennator AQ201
  • Perrenator V43-5
  • Perennator 788
  • Dow Corning 791
  • Wacker Elastosil 4300 (same as Elastosil 121)
  • Perfecto
  • Dap
Supposedly GE is making a lot of this stuff according to other forums, including AGA.

The Wacker (pronounced "vacker) stuff is supposed to be outstanding but is not available in retail anymore, at least not in the states. Too bad because I scored one cartridge in black and I needed a few more to finish my project.

Perennator is German like Wacker and is available in the states but is expensive. I hear it too is a very good product.

Tip: google the bar code to anything and it useraly pops up. Then you can see who sells it.
 
Does GE Silicon I come in Black, or just Clear? I would like to find a cheap consumer grade Black silicon that's safe, and in the local Home Depot I basically have a choice of Silicon I or Silicon II, or the tiny tubes of DAP Aquarium, lol.

My last two builds using custom backgrounds I had to order 4-6 tubes of Perfecto Black Silicon from the LFS which cost much more then I expected for silicon sealant.
 
so, is it ok to use the RTV108 for a 45g hex tank? I see that it can be used for super huge aquariums, would a small aquarium pose a problem?

I'm not trying to be rude but what would you think??? If it can hold a 500 gallon tank why wouldn't work for you. Again not trying to be a smart ass.

Think about this:
You can always go down, but you must never go up!
Meaning, you can always exceed recommended standards, but NEVER, NEVER, NEVER go less than the recommended standards.1
 
In order to answer as many questions to this subject in one shot, here goes: I spoke with the company that manufacturer the stuff. They (momentus.com) purchased this from GE. I spoke with them today. This is what I received:
RTV108 is a commercial product. The consumer equivalent for this is GE silicone I.
Their STTRONGEST FDA approved is SCS1201 clear silicone (7.81 ea)
SCS1202 black silicone (same price, only sold by case)
This should answer quite a few questions

Cool. Thanx Rico.
The fact that it's FDA approved is a great start. It basically means that after cure it can contact foodstuffs to a certain percentage without worry of leaching anything harmful. Now find out about the technicals such as tensile strength, etc and you're ready to go. That's how I ended up using Dow 732.
 
As far as tensile strength, I feel pretty comfortable that it can be used in commercial building construction for water retention, water proofing, excellent adhesion to glass, cement, brick and others. I will definitely compare of course. Thanks for the heads up.
