MDF in natural state is pretty acidic. Usually they use an acid free adhesive to lessen the effect. In the open it should be OK. -- ***ATMFAQ***DIFAQ***Kitchen Sink***

I'd mount it on 1/2 foam core or ultra core( really thick sizes) then attach it to the MDF but if the print isn't a big deal you can get away with mounting it directly. They even have self stick foam core for large prints.

Sorry didn't see your reply. Here is one place, I can't vouch for them but seems they have a good variety, ver going to the local art or crafts store »www.foamcoreheaven.com/
