: Does anybody have an msds for raka 127 and 350 hardener? I have an organic
: respirator, but am wondering how bad it would be for the rest of my house
: if I use this in the basement. Thanks.

Epoxy generally isn't all that bad health wise as long as you don't breath the fumes directly or get the stuff on your skin. I work in the basement and never can smell it at all upstairs regardless of the process. Bad idea sanding uncured epoxy and once it's cured it's pretty much just dust, that's not a good idea to breath but has no other health concerns, unless you're alergic to it.

Call Raka, they have to provide you with the MSDS sheet if requested, likely can be sent via email or fax.
