Thick Film Optical Coatings

  • Hard Coatings
  • Antiglare Coatings
  • Antifog Coatings

Hard coatings improve durability, and diffusion antireflective coatings (i.e., antiglare coatings) control surface reflections of optical substrates.

Thick film coatings include hard coatings, hydrophilic (antifog), and diffusion antireflection hard coatings (antiglare). Hard coatings are typically used to significantly improve the durability of acrylic and polycarbonate substrates. Dontech has several families of thick film coatings for plastic substrates. They are designed to satisfy a range of performance requirements for plastic substrates. All of the coatings are not necessarily appropriate for all substrates and applications. Careful selection of the coatings is required to achieve the desired results. Custom coatings and specially formulated permutations of existing systems are available upon request.

8 Series – UV cured, moderate scratch and abrasion resistance, high transmittance, very good optics

9 Series – UV cured, high scratch and abrasion resistance, high transmittance, very good optics

10 Series – Thermally cured, very high scratch and abrasion resistance, high transmittance, fair optics (i.e., will highlight flaws in base material)

11 Series – UV cured, good scratch and abrasion resistance, high transmittance, very good optics

Dontech application engineers can recommend the thick film coating best suited for your application. For additional information on thick film coatings, please contact a Dontech applications engineer, or request that a hard copy of the Windows Design Guide be sent to you.
