Since folks here are talking about silicone caulking in general, does that mean that the talk of "aquarium safe silicone" is overrated?Has anyone had the opportunity to use and compare the following silicone sealants?
Some better than others? Failures? Recommendations?
Supposedly GE is making a lot of this stuff according to other forums, including AGA.
- 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)
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.
Lol where did you get this info?? It definitely does not cure with vinager.GE II sometimes had mold inhibitors, and sometimes not, but it does cure with ammonia and that is the problems when done in large quantities that don't have time to cure (weeks).
GE I cures with vinegar, so even if not cured, all it does is the equivalent of carbon dosing.
