The Emisshield product was
originally developed by NASA
to protect space vehicles. In
these applications, the coating
is designed to modify the sur-
face of the substrate on which
it is placed to increase the emis-
sivity and therefore the amount
of energy radiated from it. In
space applications, temperatures
can range from sub-zero to over

The Emisshield coating was
designed to maintain adhesion
and not lose its emissivity under
