It is generally accepted that paint and powder coating processes suffer from the overspray that builds up on hooks, racks and hangers. Consequences include a drop in electrical conductivity, which reduces coating adhesion, and results in a poor visual appearance. The solution is to remove the build-up as often as possible, but that’s something many coaters find hard and expensive. Chipping, burning and blasting the excess buildup of paint and powder are slow, labor-intensive processes that end up damaging the hooks and racks. Furthermore, swapping out hangers and racks so they can be cleaned in an off-line process creates downtime which is another expense that most in the industry would like to reduce or eliminate.
