ELECTROPOLYSEAL® III

ELECTROPOLYSEAL III uses a conventional zinc phosphate base, which is applied via the barrel immersion process. The POWERCRON® XL cationic electrocoat product is then applied via bulk processing electrolytically to the fastener. After rinsing, a torque modified post dip is then applied to the part and it is cured. The film build of this finish is 0.6-0.8 mils (or 15-20 microns).

ELECTROPOLYSEAL® IV

ELECTROPOLYSEAL IV is a unique finish of one coat of zinc phosphate base. The finish is cured at this point. This base coat of zinc-rich is then topcoated with cationic electrocoat in a bulk application. A torque modified post dip is used after the electrocoat, and both finishes are cured concurrently. The film build of the basecoat is 0.3-0.4 mils or 7.5-10 microns, and the total film build is 0.6-0.8 mils or (15-20 microns). ELECTROPOLYSEAL IV uses a dip/spin basecoat, which may make recess fill possible.

ELECTROPOLYSEAL® V

ELECTROPOLYSEAL V is a combination of a plated substrate and cationic electrocoat. The electrocoat film can be either epoxy or acrylic based. The parts are electroplated and passivated. The electrocoat is applied in bulk. A torque modified post dip can be added to this finish when torque tension characteristics are critical. Film build on the plated finish is 0.3-0.4 mils (or 7.5-10 microns). Total film build is 0.6-0.8 mils or (15-20 microns).
