The accelerated aging characteristics of an aluminized acrylic reflector material (3M Company ECP-244) were studied when bonded to either an aluminum or acrylic painted steel substrate. The aging consisted of temperature/humidity cycling between extremes of 54/sup 0/ to -29/sup 0/C. After 255 days of environmental chamber exposure, the solar averaged specular reflectance values for both types of samples indicated no degradation, within experimental errors. Therefore, the acrylic painted steel substrate appears to be a suitable substitute for a sheet aluminum substrate.
