What is weathering data?
Weathering data are the results of either exposing the colorant outdoors in the application media, e.g. exposure in Florida, Arizona, Allunga, etc or the results of artificial accelerated weathering test. The data in the MMC database is exclusively the latter in an effort to keep the information as uniform as possible. Please note outdoor weather conditions do differ and not all accelerated weathering machines are set to the same parameters.
