WRC-680 White Reflectance Coating

WRC-680 White Reflectance Coatings is a diffuse white coating for reflectance applications covering the UV-VIS-NIR wavelength region. This pre-packaged coating offers an alternative to customers with small-scale applications, or those who wish to prototype components using a high reflectance white coating.

WRC-680 is a barium sulfate based formulation that is easily applied by means of an airless spray gun or an airbrush. The coating can be applied to most metal, plastic, and glass surfaces that have been properly cleaned and roughened by mechanical means. Plastic surfaces require special cleaning to remove any mold release agents that may interfere with the coating adhesion. The coating is packaged in air-tight, one- and two-liter containers and shipped with surface preparation and application instructions.
