  • Durable protected optical coatings
    Patent number: 6361876
    Abstract: A metal substrate such as bare or anodized aluminum or an aluminum alloy having an inorganic white paint thermal control coating on the substrate, the coating having low solar absorptance and high infrared emittance, such as a potassium silicate binder having zinc oxide particles distributed therein, and a fluoropolymer topcoat such as polytetrafluoroethylene on the inorganic white coating, the topcoat having substantially no significant effect on the optical properties of the thermal control coating and having substantial adhesion to such coating and improved resistance to darkening under ultraviolet exposure in the outer space environment.
    Type: Grant
    Filed: April 28, 1995
    Date of Patent: March 26, 2002
    Assignee: McDonnell Douglas Corporation
    Inventors: Henry W. Babel, Mark M. Hasegawa, Steven A. Daneman
  • Articles with stable coatings having tailorable optical properties
    Patent number: 6331357
    Abstract: An article is coated with a mixture of a high absorptance pigment, a low absorptance pigment, a low emittance material, and a high emittance binder. Each of the components of the coating are stable when exposed to a space environment. The amounts of the high absorptance pigment and the low absorptance pigment are selected to produce an absorptance of the coating of from about 0.20 to about 0.90, and the amount of the low emittance material is selected to produce an emittance of the coating of from about 0.25 to about 0.90. The low absorptance pigment is preferably a white pigment such as zinc oxide. The high absorptance pigment is preferably a black pigment such as cupric oxide, cobalt oxide, or manganese dioxide. The low emittance material is preferably a metal such as aluminum. The binder is preferably a ceramic such as potassium silicate.

  • Process for protecting optical properties of a thermal control
    Patent number: 5885658
    Abstract: A metal substrate such as bare or anodized aluminum or an aluminum alloy having an inorganic white paint thermal control coating on the substrate, said coating having low solar absorptance and high infrared emittance, such as a potassium silicate binder having zinc oxide particles distributed therein, and a fluoropolymer topcoat such as polytetrafluoroethylene on the inorganic white coating, the topcoat having substantially no significant effect on the optical properties of the thermal control coating and having substantial adhesion to such coating and improved resistance to darkening under ultraviolet exposure in the outer space environment.

    Date of Patent: March 23, 1999
    Assignee: McDonnell Douglas Technologies, Inc.
    Inventors: Henry W. Babel, Mark M. Hasegawa, Steven A. Daneman
  • Protection of thermal control coatings from ultraviolet radiation
    Patent number: 5401573
    Abstract: A metal substrate such as aluminum or an alloy thereof having an ultraviolet sensitive thermal control coating on the substrate such as an anodic coating or a white thermal control paint coating, and an ultraviolet degradation protective coating on the thermal control coating. The ultraviolet degradation protective coating can be an ultraviolet absorber such as quartz or an ultraviolet reflector such as aluminum oxide.
