I’m sure this is a stupid question, but I haven’t used polycarboxylate cement since sim lab. I’m getting some of my required CE in online and sat through a materials lecture and the guy mentioned something I’ve never heard before. He was saying that he uses polycarboxylate cement still because it not only chemically binds to tooth structure (Yup, no problem there), but it will also strongly bind to sand blasted metal, etched ceramics, and CHEMICALLY BINDS to PMMA and resins.

Is that right about it chemically adhering to PMMA and resin? That just doesn’t sound right to me, and he didn’t go into any detail.
