Heresite Protective Coating | The DECC Company

Specializing in phenolic resin barrier coatings, Heresite Protective Coatings are used across a variety of industries to combat atmospheric and chemical corrosion. Typically applied to much larger components, DECC utilizes Heresite’s coating to combat sulfuric corrosion from exhaust gas recirculation in commercial diesel components.

Coating Descriptions


Heresite's P-403L high bake phenolic has been the industry standard for protecting rail cars and storage tanks that transport chemicals from corrosion. P-403L offers excellent resistance to solvents, acids and salts, including 70-98% sulfuric acid at temperatures up to 120° F, which is why DECC applies it to aluminum castings in diesel EGR systems. P-403L is the ultimate coating choice to protect components where pH< 9 is likely to be encountered.
