CLAREX Hard-Coated Optical Grade Cell-Cast Acrylic Sheets (RH)

Hard-coating adds scratch and chemical-resistance.

The CLAREX hard-coat can be added to the surface of the sheets for increased scratch and chemical resistance, as well as for a base layer for optical coatings. But this is not your typical abrasion-resistant coating. The factory has developed a unique process for applying the coating, which maintains the optical grade properties of the acrylic sheets, as well as the ability to apply the hard coat to their non-glare textured surfaces without affecting the surface texture properties. Say goodbye to the surface defects typical of flow/dip/roll coated acrylic sheets…the CLAREX hard-coat is truly optical grade. The hard coat is acrylic-based, outdoor (UV) stable, and will not delaminate.

Benefits:

• Scratch resistance improved from 2H to 6–8H pencil hardness
• Enhanced chemical resistance
• Excellent machinability and laser-cutting performance
• Maintains same optical-grade properties as uncoated CLAREX sheets:
  • Low wavefront distortion
  • High light transmission – 92% for clear sheets without anti-reflective coating
  • Isotropic transmission
  • No birefringence of double refraction – no retardation of polarized light
  • Virtually no autofluorescence (due to pure liquid monomer)
  • High long-path transmission
  • High molecular weight (2+ million)
  • 100% visually inspected for defects
• Ideal base substrate for adding optical coatings

• If we don’t already have the color you need, color-matching is available
