A black paint has been developed and tested for cryogenic applications involving wave-lengths beyond. 10μm. The paint has been used extensively for liquid helium cooled applications in a variety of instruments operating between 10 and 120pm. The material is applied by brush over a spray or brush applied primer coat. A final covering is applied by either brush. or spray. The composition and preparation of the paint are described, as are data about its outgassing properties. Infrared reflection and scattering data obtained by other groups which compare this material to other commercially available surface preparations are presented.
