Technology

Overview:

Brisbane Materials has four novel and proprietary XeroCoat® materials platforms:

  • Anti-Reflective Coating (ARC) – porous silica layer made from liquid precursor at room temp
  • Anti-Tarnishing Coating (AT) - non-porous glass coating made from liquid precursor at 150-180°C
  • Inorganic Adhesive (GL) – liquid-to-glass glue replaces epoxy and silicone adhesives
  • Inorganic Binder (PH) – developed as replacement for silicones in LED leadframe and CoB

 

XeroCoat® ARC Features-Benefits:

  • Quarter-wave ARC reduces reflections by 75% or more on glass or plastic lenses and covers
  • Applied by spray coating, with room temperature curing; automated equipment available
  • Increases candela up to 30% on textured lenses
  • Increases lumens up to 6%

XeroCoat® AT Features-Benefits:

  • Aluminosilicate glass coating made from two-part liquid precursor
  • Reduces light output loss caused by sulfur tarnishing, tested per ASTM B809
  • Viscosity ~2 cps; apply by jetting and / or dispense; cured at 150-180°C for 30 min
  • Refractive index variations 1.45 – 1.54; extinction coefficient <10-3

 

XeroCoat® GL Features-Benefits:

  • Lithium silicate glass made from liquid precursor
  • Silicone / epoxy replacement enables higher temp LED operation with improved reliability; works on ceramic phosphor (PiG), GaN, sapphire, glass, and most ceramics. Stable to UV-C.
  • Viscosity variable ~2 – 100 cps; apply by jetting and / or dispense; cured at <180°C for 30 min
  • Refractive index ~1.45 – 1.49; extinction coefficient <10-3

 

XeroCoat® PH Features-Benefits:

  • Aluminosilicate glass made from liquid precursor
  • Silicone binder replacement higher temp operation with improved reliability
  • Viscosity variable ~10 – 100 cps enables easy phosphor dispersion; cured at <180°C for 30 min;
  • Refractive index ~1.45 – 1.49, extinction coefficient <10-3
