Application Method
Customer needed a solution requiring minimal effort from labor. Access was only by wire rope and staging basket. Abrasive media blasting was not allowed. An MBX Bristle Blaster was used to acquire a surface profile of 3 mils. MEK was used to clean and degrease the application area. Then one high-build coat of Belzona 1331 was applied by brush in one staging. The application was carried out in accordance with a modified version of Belzona System Leaflet CEP-4 and Belzona 1331 Instructions for Use.
Belzona Facts
Belzona 1331 offers outstanding erosion-corrosion resistance. In addition, because of its chemical resistant qualities, the salt environment along the coast proves no match for this coating. Being a high-build coating, this application was carried out in one single pass, thus keeping labor and downtime to a minimum.
