Principles and Formulations of Solar Reflecting and Low Infrared Emitting Coatings for Defence Use.

摘要

The near infrared (NIR) reflectance of paint schemes may be increased by replacing dark pigments which are highly absorptive in the visible and infrared regions, by visually similiar pigments with low NIR absorption. On exposure to sunlight, these low NIR absorbing pigments reduced heat buildup and thermal infrared (TIR) signature. Resins also absorb and emit radiation, frequently in the thermal infrared region. This report covers the formulation of coatings to reduce heat buildup, prolong Service life and control infrared emission from Defense equipment. A number of Service requests are cited to illustrate solar and infrared requirements. Australia. (AW)
