Reef Safety of Polyurethane Foam

[YankeeTankee]

Marketed for fish ponds, I know some reefers have used it. Randy can you think of any chemical issues over the long term with a polyurethane foam in the tank?

I've seen people use It in the past go glue live rock together but i think it was said that it goes brittles from exposure to UV light

I don't see any ingredients that I'd overly worry about once it is cured.
