A Coating That Cools and Cuts Costs

Issue: 2004
Category: Industrial Productivity/Manufacturing Technology
Page: 95-96
Center: Ames Research Center
State: VA Manufacturer: Wessex Incorporated
Origin: NASA Protective Coating for Ceramic Materials

To enable low-cost space access for advanced exploration vehicles, Ames Research Center invented and patented a protective coating for ceramic materials (PCCM) in 1994. Wessex received a license for PCCM in 1996 and initially applied it to building materials for firewall applications. Through further testing and experimentation, however, the company would eventually come to learn the true potential of PCCM, leading to longer-lasting materials, greater energy conservation and fuel efficiency, increased productivity, and significantly reduced operating costs for numerous U.S. businesses.

Known commercially as Emisshield,T Wessex's PCCM product mirrors NASA's original protective coating in that it provides increased "hemispherical" emissivity-the ability to absorb energy and reradiate it to a cooler surface, body, or atmosphere. Like PCCM, Emisshield can be reused and repeatedly cycled between severe extremes of subzero temperatures and temperatures over 3,000 ?F, without ever damaging the protective coating or the underlying material. With each use, the coating's molecular structure is rearranged to create a stronger bond between the coating and the underlying material, and an even greater level of thermal protection. Wessex has embraced a high rate of success with Emisshield beyond its initial fireproofing accomplishments.

Finding a balance between military necessity and humanity. These include: • the rule of distinction requiring that a distinction be made between civilians and combatants and between civilian objects and military objectives; • the prohibition of indiscriminate attacks requiring that attacks must be directed at military objectives; • the rule of proportionality requiring that the effect of the attack on civilians and civilian objects not be out of proportion with the military advantage gained; • the rule on feasible precautions requiring that care be taken to spare civilians and civilian objects; • the rule on environmental protection prohibiting using means of warfare that cause damage to the environment; • and the rule on superfluous injury or unnecessary suffering.

NASA TV Schedule brought to you.

NASA TV Multichannel Broadcast includes: Public Services Channel (Channel 101); the Education Channel (Channel 102) and the Media Services Channel (Channel 103). › Watch NASA TV on the Web › View NASA TV Monthly Education Schedule › View the regular NASA TV Daily Program Schedule for the Public and Media Channels Programming Notice: All NASA Television Channels (Public, Education, Media, occasional HD feed and the Live Interactive Media Outlet) are now available on Satellite AMC 3. Cable and satellite service providers, broadcasters, and educational and scientific institutions need to re-tune receiving devices to AMC 3 to continue accessing NASA TV. "News networks, their reporters, and other broadcast media organizations must tune their satellite receivers to the Media Channel to ensure reception of clean feeds for all mission coverage, news conferences, and other agency distributed news and information. News and other media organizations will no longer be able to rely on content from the Public Channel for clean feeds of mission and other agency activities." For complete downlink information for Satellite AMC 3 please see “Important Information” at: The programs listed below are changes to the regular Daily Program Schedule.
