Transparent, flexible scratch resistant coating/material?
Transparent, flexible scratch resistant coating/material?
(OP)
I need something that can protect clear plastic from getting scratched and has to be scratch resistant vs sharp aluminum objects (tensile strength ~ 250MPa) so it should be reasonably hard. The problem is that most transparent scratch resistant materials (like glass) are too brittle - I need this thing to have 1.8% elongation or better.

Something as hard as harder than aluminum would be necessary.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

RE: Transparent, flexible scratch resistant coating/material?
Sometimes coatings can be less flexible than the substrate itself, which gets really ugly if it's flexed enough to make the coating develop a bunch of little cracks.
