Application Situation
Compliant non metallic structural reinforcement repair on process lines.
Application Method
Surface preparation performed in accordance with NACE 2(=ISO 8501-1, Sa 2 1/2), through dry abrasive blasting to white metal with Sponge Jet system. Average surface roughness achieved of 89 microns. After surface preparation and cleaning, Belzona 9611 was used for emergency leak sealing in some areas, followed by Belzona 1111 to fill pits and smooth out application area. Belzona SW II system was then applied over the repair area for structural reinforcement of the equipment.
