Finishing Systems Available for Enclosures

Standard Finish - phenolic primer gloss epoxy finish coat
Primer - 83040 Industrial Phenolic Primer applied @ 1.5-2.0 mils dft.
Finish coat - ClovaCoat 300 high build epoxy applied @4-6 mils dft high gloss finish.
System advantages: Primer adheres well to satin coat steel. Good corrosion resistance. Topcoat is very tough. Resistant to weather, moisture, solvents, salt water, fresh water, abrasion, acids, alkalis, oil.
System disadvantages: Top coat tends to chalk especially in dark colors, however this does not affect coating performance.

Optional Low Gloss Finish - phenolic primer gloss epoxy finish coat
Primer - 83040 Industrial Phenolic Primer applied @ 1.5-2.0 mils dft.
Finish coat - 83150 ClovaGuard high build epoxy applied @4-6 mils dft low gloss finish.

System disadvantages: This system is approximately twice the cost of standard system above.

Economical Finish - (not recommended) phenolic primer and industrial enamel top coat.
Primer - phenolic primer
Finish coat - Industrial Enamel high gloss finish
System advantages: Primer primer adheres well to satin coat steel and has good corrosion resistance. Low cost top coat good for very mild exposure.
System disadvantages: Top coat does not afford much protection. Low chemical and moisture resistance. On roof structures where water pools it can fail.

For severe exposure a minimum SSPC-Sp6 commercial blast is recommended for structural steel base framing. This removes contamination and a large portion of mill scale leaving a good surface profile. Clovaprime 21 is recommended to cover the blast profile and then Clovacoat, Clovaguard or Clovathane can be used.
