CathoGuard 800 relies on cathodic epoxy chemistry cross-linked with blocked isocyanates. Upon application of an electrical potential, the resin particles migrate to the cathode (the part) and deposit a uniform insulating film. The “High Throw Power” formulation ensures that the coating penetrates deep into box sections where Faraday cage effects usually hinder coverage. The cured film exhibits high chemical resistance and serves as a superior substrate for topcoats.
