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.
Benefits:
- Even more scratch resistant than the standard hard-coat
- Optical Grade Cell-Cast Acrylic
- Coating on one or both sides
- Available with 9H SUPER-Hard-Coat on one side and 6-8H Standard Hard-Coat on the second surface for improved impact resistance
- No retardation / no birefringence
- Available with non-glare textures
- If we don’t already have the color you need, color-matching is available
Common Applications
- Protective window for flat panel displays
- Scanner bed windows
- Barcode scanner exit windows
- Camera enclosure windows
- Machine vision
- Sensor windows

Customization
Custom sheets & parts to meet the needs of your applications.
Build your own sheets. Do you have a unique design requirement that cannot be met with off-the-shelf UV filter sheet materials? CLAREX acrylic can be fully customized and produced from low-volume runs to mass production. Select thickness, formulation, additives, pigments, textures, surface coatings, and optical coatings to create thin acrylic sheets tailored to your application.
Typical lead time is 4–8 weeks. Finished parts and assemblies can also be fabricated to specification.
