Permeation of Chloride and Sodium Ions through Protective Coating for Naval Shore Structures.
Abstract
A method of measuring the permeability of salt ions through a paint film by the radiometric method is described. The method is precise and sensitive and is also useful in the investigation of other parameters which influence permeability of salt ions through paint films. Unpigmented films evaluated were: alkyd, silicone alkyd, epoxy, epoxyester, polyurethane, styrenated alkyd, and ethyl cellulose. System coating films (multicoated paint systems consisting of a primer or intermediate paint or both, top-coated with a finish coat, were also studied. These films included epoxy coatings, vinyl coating, and an inorganic zinc coating. (AH-PL)
