Avian-B White Reflectance Coating

Water-based high reflectance barium sulfate coating

Avian-B coating is a water based barium sulfate coating, primarily designed for laboratory applications. The coating is highly lambertian and exhibits reflectance of >97% over from 350-850 nm and greater than 92% from 250-1300 nm. When applied, the coating is stable from -40 degrees C to +90 degrees C. The coating is easily applied to most metal substrates and can be applied to other materials with proper surface preparation.

Avian-B is a well characterized coating that has been used for diffuse reflectance applications for more than 20 years.

Avian-B coating is available as either bulk coating or as coating services. Bulk coating comes shipped with preparation and coating instruction. The bulk coating ships without the alcohol propellant/co-solvent. Once propellant/solvent is added, one liter of Avian-B premix coating makes approximately two liters of finished coating.
