First, the Switch Gear Boxes were coated with Belzona 3921 Conditioner that is zinc rich and also acts as a corrosion ihibitor. Then, Belzona 5111 was then applied for the finish UV protection and final enviornmental protection. The application was carried out in accordance with the Belzona System Leaflet CEP-4 and Instructions for Use. 
Belzona Facts
These units were corroding at a fast pace. In 3 years of service, evidence of through-wall had already become apparent and asset replacement was becoming a consideration. The customer tried other coatings to offset corrosion, but they fared no better than the original coating. Then Belzona 5111 and Belzona 3921 system was given an opportunity. After testing for one year, customer was happy with no visible signs of corrosion! A company decision was made to coat all the Switch Gear Boxes with Belzona. Spend a little now, save a lot later!
