Absorptivity values for various color paints

Hi. I need the absorptivity values for RAL7030 (light grey) and RAL2000 (yellow orange) paint coatings for a thermal analysis run. I work as a thermal design engineer for an electronics company in Turkey. The application is a set of packages to be designed for a toll booth on a highway.

Best regards

The values will be specific to the paint formulation.
I think you will have to ask the manufacturer.

Mr. Alpsan, I doubt that the manufacturer is going to have this information because it isn't needed for anything. You want to measure the rate that paint on a toll booth (or toll booth accessories) absorbs or retains heat?
