Horner Industrial Coatings recently addressed an issue concerning a steel mill exhaust fan that required coating following modifications to its design. The customer reported encountering challenges related to particle accumulation on the backside of the fan blades due to the structural design of the gussets supporting each blade. In response, our Fan/Fab team redesigned the support structure and conducted all necessary welding tasks prior to coating. Given that the blades were already hard-faced, our standard process of applying a hard coat was deemed unnecessary. Instead, we opted to coat the entire fan with a zinc-based wire, effectively galvanizing it and providing protection against corrosion in the harsh operating environment. Subsequently, the entire fan was coated with an air-dry, non-stick coating sourced from Loctite. This coating serves to mitigate the adherence of particulate matter to the fan blades, thereby reducing the likelihood of future balance issues. It’s noteworthy that we are currently participating in a testing program for this new Loctite product, as we are one of their select authorized applicators.
