CLAREX SUPER-Hard-Coat Acrylic (RHG)
Even higher scratch resistance than the standard hard-coat
The CLAREX SUPER-Hard-Coat has 9H pencil hardness which is a step up from the standard hard-coat which has 6-8H pencil hardness. The tradeoff is that the sheets do become more brittle, and more expensive. So they work well for high abrasion applications, but not so well if there will also be impacts.
