Structure-scratch properties relationships of acrylate photo-polymerizable protective coatings for thermoplastic substrates

- Micro-scratch tests enable a finer differentiation of the coatings than DMTA.
- The crosslinking density plays a part in the scratch resistance.
- Nanoparticles did not modify the properties of the coating.
- Bio-based coatings show a better scratch resistance than petro-based counterparts.
