Z302 became less obtainable when the manufacturer required expensive massive drums of the black specular paint as the minimum order. As they no longer accommodate customers with pint-sized needs, companies, such as the National Institute of Science and Technology (NIST), are searching for a replacement. PT401 has been used on previous projects with satisfactory results. In accordance to requirements from NIST, a process for painting with PT401 8-10mils thick will be developed, and adherence, durability and specular reflectance and diffuse properties in the infrared will be documented.
