Applying Spray Coraflon® to Steel


The AAMA 2605 G85, Annex 5 cyclic corrosion scribe creepage specification was met on 2-3 mil blasted cold rolled steel using the PCS79102OG primer top coated with a Coraflon top coat with a total coating film thickness of about 7 mils. 
 
On B1000 steel control panels, the AAMA 2605 cyclic corrosion scribe creepage specification was met using the PCS79102OG primer top coated with a Coraflon top coat with total film thicknesses in the 5-6 mil range. 
 
Coraflon powder does not pass the G85, Annex 5 cyclic corrosion test as a one coat system without a primer.  Scribe creep will not meet specification with 1,000-1,500 hours of the 2,000 hour duration test. Precaution should be taken when buildings are exposed to severe environments such as seacoast, road salt, fertilizer or any other corrosive areas.
