[quote= I've discussed this topic at length with someone who had researched silicone for the aerospace industry when it first came out. Silicone I is food safe and therefore is safe.[/QUOTE]
I agree to a cretin level. Food safe silicone is more of a pain and needs cleaned and washed more after it first cured and is rated on a water resistant with out the release of arsenic or formaldehyde not compete submerse of it's self for permanent use under water. It is not pure silicone it will break down faster than normal because of the things that are put in it to repel mold break down the silicone its self. If it did seal in the the toxins that repel mold and mildew than it wouldn't repel mold now would it? Making it food safe under specified conditions which are not the same conditions of a animal habitats that deal with consent 100% percent exposure to water dose not make it safe for the type of use that it is being used for. Stop listening to hearsay and go by facts , READ the MSDS sheets on these products. As far as solvents in the silicone they are pushed out to 99% percent in the curing possesses I do agree with you on how the solvents work in the silicone it self to cure it self.
The silicone that you are using will not immediately kill the animals but over time like all carcinogenic materials will do its damage over time.
Also I forgot to state this above but, the silicone will mold because of the break down of the top 1/10th layer of the silicone will have released all of the mold fighting properties in it but, this takes the better part of ten years to happen.
The amount of release of these mold fighting properties is and meets health standard's for human exposure levels not a two ounce frog or a two pound turtle. This was a 20 point question on my OSHA certification test for the UNION. Mind you there were 240 possible point to score on this test.
