I am not a chemist but I try learning through open sources. I am trying to develop a product by using Diurethane Dimethacrylate.

There are already products available in the market that use this resin along with cetyl alcohol. The property that the compound exhibits is slight hardening when exposed to light cure (Used in Dental procedures). This hardening happens in a way that it can be easily peeled off from the tooth surface.

My question are:
Which other resins would exhibit such properties?
Can PVA be used instead of cetyl acohol?
