Reading the thickness of the applied coating

using Dry Film Thickness GaugeReading shows 320 microns equivalent to 0.32 mm

Reading the Surface Temp on metal roofing with out

Astec Ceramic Coatin

Reading shows average of 54.05 degrees Celsius on

the surface of metal roofin without astec coatin

Reading of Surface Temp was also takenunderneath metal roofing applied with astec coating

Reading shows 41.3 degrees Celsius taken underneaththe metal roofing, a decrease of 2 degrees celsius

Reading of Surface Temp on metal roofing Applied

with Astec Ceramic Coatings

Reading shows ave. of 41.5 degrees Celsius ,a

decrease of 12.55 degrees celsius before and after it

was applied with astec ceramic coatings
