As of early June, new Mount Cor products will all have acid-free properties.
That's a fair question, since Mount Cor is truly permanent and therefore unacceptable for preservation framing. The primary competitor, Kool Tack, is fully reversible without invasive chemicals or procedures, so it is considered to be preservation-worthy.This is an honest question; why do we need AF Mount Cor or anything that is an AF backing if it is being permanently heat mounted?
Much in agreement with this. I love being able to mount with 130 degrees, as even 150 still seems to make a color difference sometimes.....Even so, there certainly is some benefit in working to extend the useful life of non-preservation framing...
