  • Black molecular adsorber coating system
    Patent number: 10787575
    Abstract: A black molecular adsorber coating (MAC-B) composition is provided that exhibits adsorptive capabilities and reduces the effects of optical path degradation and system performance degradation when formed into a black coating having low reflectivity. The coating can be used in stray light control applications or within light paths between optical systems to absorb light and reduce the effects of optical path degradation. The coating can be used in vacuum systems to adsorb molecular contaminants and to reduce vacuum pressure levels. The coating composition can be sprayed onto interior surfaces, such as optical cavities of cameras, telescopes, lasers, baffles, detectors systems, and electronics boxes to control performance degradation due to outgassed molecular contaminants.
    Type: Grant

  • MOLELCULAR ADSORBER COATING
    Publication number: 20120034384
    Abstract: A molecular adsorber coating for collecting and retaining outgassed molecular effluent may include a mass fraction of about 0.20 to about 0.40 of zeolite, a mass fraction of about 0.40 to about 0.80 of a binder, and a mass fraction of about 0.0 to about 0.30 of water. The mass ratio of the binder to the zeolite may be in a range of about 1.6 to about 2.4. The binder may comprise, on a mass basis, about 30 to about 40 percent particles of nonporous silica dispersed in a liquid phase.
