ASTM G85 is another salt fog test called Prohesion. A modified version of this test cycles between salt fog exposure and QUV exposure. Some have suggested that prohesion yields results more comparable to real world exposure....
Have The Corrosion Protections Of The FEVE Coatings Been Measured Without A Primer (i.e. Direct To Metal)?
Yes. This work is underway currently. ...
Did You Test The FEVE Coating On Sulfuric Acid At Lower Concentrations?
Yes. We tested Sulfuric Acid at 50% in a 1 hour spot test. We also tested 10% Sulfuric Acid in a 30 day immersion test. We saw passing results in both tests....
Do We Need To Remove The Rust Before Applying The Coating?
Yes. Proper preparation of the substrate is critical for long term performance....
What Kind Of Protection Can Be Expected For Long Term Exposure (Submerged) Below A High Water Line?
FEVE based coatings are currently being used on concrete substrates submerged in water....
