Mixing Shafts

A retooling subcontractor needed substantial, lasting protection on four 5’ tall mixing shafts. In use, the shafts are connected to polyurethane mixers and immersed in a chemical separating tank where they agitate heterogeneous mixtures of chemicals to draw out pure chemicals.Originally the shafts had been coated with an epoxy, but the coating was quickly degraded by the chemicals and the shafts began to rust. The retooling sub-contractor then tried outsourcing the protection to a urethane coatings company, but this polyurethane material didn’t hold up over time. The shafts needed to be protected by a product that had high chemical resistance and wouldn’t flake or melt off into the chemical bath.
