*B-1: Polane™ Carbide Black, matte ~ .0004” to
.001” thick. 2-4% reflectivity in the visible region and 96-98%
emissivity up to 2.5 micron wavelength in the infrared. Vacuum
compatible.
*B-2: Ultra Black, ultra matte, ultra deep
unbrushed black ebonol. The surface is delicate and can acquire
light sleeks even with the best of care, but several of these
sleeks have negligible effect on the total reflectance. Vacuum
compatible.
Krylon™: Standard " Krylon™ Ultra-Flat ".
This is an excellent finish with emissivity above 95% for visible
and infrared up to 16 microns. It is applied over our base B-1
coating.
Aeroglaze™: This coating is used only as a
custom at this time. It is slightly deeper black and has somewhat
less hemispheric reflectance than our standard B-1. (Vacuum
compatibility unknown).
White: Polane™ Flat White. This coating is used
for reflecting and diffusing visible radiation. Vacuum compatible.
*Standards are B-1 and B-2. Krylon™ 'Haze' overcoat is frequently
used and is applied in-house for undelayed turn-around. Others are
occasional customs that have been utilized.
Coating Selection Guide
In choosing a coating for subsequent use on a product it is
recommended that you try out your closest estimate to make sure
the absorption (or emissivity) is adequate for your application
and that the hemispheric reflectance is allowable.
