Why you shouldn't use GE I Windows and doors

[Clay]

It's actually a GE (or was before GE sold off part of their product line to Momentive) silicone product as well. It's called RTV108, however, the last number indicates the color. 102 is white, 103 is black, 108 is clear.

Ok, but both of those links you provided, one tube costs more than double what you pay for GE I at HD or Lowes...

And neither of those say they are safe for aquarium use. They just don't say not for aquariums in the data sheet.

there has been plenty of debate on this subject and ge1 is very well accepted as a good form of silicon for resealing tanks

It says not to use on aquariums to avoid any liability issues. I haven't heard one person whose fish were poisoned by GE 1 silicone. And yes, 100% silicone is the same no matter what brand. If the silicone is not pure silicone, than you run into problems.

This thread is useless. Everyone knows GE silicone 1 is aquarium safe and cheapest thing you can get. This has been debated way too many times before and it has been proven over and over again that it is aquarium safe.

silicone is silicone

Actually, 100% silicone is 100% silicone

And yes, 100% silicone is the same no matter what brand. If the silicone is not pure silicone...

There is a little bit of misunderstanding about silicone and what it really is. What it isn't is 100% silicon. It isn't the stuff that is used in computer chips and it isn't what glass and sand are made of.

The element on the Periodic Table is silicon (no 'e'). It is what computer chips are made of. It is also the notorious component in glass and sand. It is also a component of silicone (spelled with an 'e').

Silicone is a formula for a polymer. That formula can vary from manufacturer to manufacturer, brand to brand, or even product to product under the same brand. That is why a silicone product with mold inhibitor added to it can still be called 100% silicone. I tested the adhesive strength of different brands a while back and it is clear that each brand is a different formula. The properties are even different in the cured rubber.

This is 100% silicon:

AGREED!
