I don't have any direct experience with the Lexan brand, but our local plexi
supplier can order their product with a scratch-resistant coating on one or
both sides. The only down side they said was that once it has the coating,
it cannot be glued. If you have just one face and not a box, then you should
be OK. As far as I know, plexi is safe in an artifact environment,
especially since we frame works and make vitrines with it. You might contact
an objects conservator to see if they have done an Oddy test for Lexan or
other plexi brands with the type of materials you will have on display. I
would contact a couple of local suppliers and see what products they have
and see what some of their fabricators say. From another viewpoint,
depending again on size and whether it is just a front and not a case, you
could also explore laminated glass. We have 3 cases which are only viewable
from the front which use large sheets of laminated. Yes, they are heavy and
expensive, but they are safe and durable and have been on display for 3
years now without a scratch. If you go that route, invest in some suction
cups from somewhere like Sommer & Maca.

Subject: [MUSEUM-L] Question about plexi-glass
Hello Listers, I hope everyone is well on this Tuesday afternoon J. I
have a question about acrylic case fronts and bonnets for cases. I'm
working with an exhibit designer who insists on installing Lexan on a case
front. I believe it was explained to me that it was "bullet proof." From
my experience, it scratches easier than other types of acrylic. What is the
best material to use? What is the most scratch resistant and durable? Is
Lexan safe in an artifact environment? Any words of advice would be greatly
appreciated!
Thank you,
Ava R. Wilkey
