Abstract
This paper contrasts the weathering performance of 2 popular classes of pre-colored thermoplastic resin systems - acrylonitrile-styrene-acrylate (ASA) and ASA/PC (bisphenol-A polycarbonate), in standard automotive black colors. The performance trends observed in actual Florida and Arizona outdoor weathering are contrasted to their performance under the SAE J1960 Xenon Arc Accelerated Weathering Protocol to illustrate the difficulties of correlating performance trends observed under artificial conditions to actual outdoor exposure. Based on the results of this study and those of previous authors, suggestions for modification to the SAE J1960 protocol are offered that might reduce the variability of test results.
