Why is COLOURCOIL Kynar 500 resin type paint system the best choice for a cool metal roof coating?
The proven durability of full strength 70% Kynar 500 resin type paint systems allows for stable color and film integrity over decades of exposure. This durability is also seen in the retained amount of initial solar reflectance. Thus, paint systems based on the Kynar 500 resin have a surface that does not retain dirt, remains cool, and retains its original color better than any other resin type. In the design and performance of a building, the owner wants to know that the initial energy cost savings projections are maintained over the life of the roof. Most other roof types have been documented to lose some percentage of their initial solar reflectance due to dirt pick up and overall degradation from the weather. In those cases, the aged performance of these cool roofs is far from what the building experiences in the early years. The strong performance of Kynar 500 based paint system which is maintained over time is especially apparent in the retention of the initial solar reflectance
