expanding foam toxicity

[aramcheck]

I am currently working on a new viv project with a glass separation. I am planning to "glue" some corck bark to the separation and fill the cavity created with expending foam so I do not create a bacterial nursery...

The expending foam I found at the local diy shop is Polycell Expending Foam, which is labelled as an irritant. I am wondering of the safety of using it in my viv. I guess the irritant effected is for the uncured product, that then becomes inert once cured, am I right to believe that? Will it be safe once cured?

Yes, it is the uncured product which is an irritant. During curing, it produces a polyurethane polymer, which should be inert & safe. A friend of mine makes masks using expanding foam, and hasn't had any skin problems from wearing them...

You should make sure that it's throughly aired and washed to get rid of any residues, though.

There's a safety data sheet for the product here:

Cheers Caleb,

That's what I though, but it clarifies it all. Ta.
