TechXT-AR Large-Format Acrylic Sheets with Anti-Reflective (AR) Coating
For applications requiring large pieces of anti-reflective acrylic coatings, we stock large-format extruded acrylic sheets with hard-coat and anti-reflective coats on both sides.
These sheets start with commercial grade clear extruded acrylic, followed by flow coated hard-coat on both sides, and are finished with a vacuum deposition multi-layer anti-reflective coating on both sides. An additional oleophobic coating is added to both sides to make it easier to keep the material clean. The result is a clear acrylic sheet with very low reflections (<2%) and high transmission (>98%) across the visible range. We stock the sheets in large sizes, typically 48 x 96″, so these are well suited for larger display applications.
Note: This is not CLAREX brand material
