Abrasion-Resistant / Scratch-Resistant PMMA
Abrasion-resistant/scratch-resistant PMMA is produced by applying a hard coat (such as silicon-based, acrylic UV-curable coating, or nano-ceramic coating) on the PMMA substrate surface, or by co-extrusion to form a wear-resistant layer on the PMMA surface. Surface pencil hardness can reach 2H~4H (vs. HB~1H for untreated PMMA), with abrasion resistance improved 5~10×. It is widely used in applications with frequent contact or cleaning, such as electronic touch panels and automotive interiors.
