843TECHNICAL DATADATA SUBJECT TO CHANGE WITHOUT NOTICE.When the organic finish (Protective Layer) is breached through to the ferrous metal substrate, moisture, air, minerals, and surface contaminants, combine to create electrolytes allowing electrical current to flow by the movement and discharge of ions according to the Faraday%u2019s law of electrolysis. Moisture (electrolytes) will immediately penetrate any breach in the coating surface. As the coating is lifted by the growth of corrosion undercutting, a greater amount of moisture is trapped beneath the coating barrier and will prolong the electrolysis process thus accelerating corrosion reaction.The conditions that cause corrosion to happen are well known. The conditions, materials, and processing methods required to prevent corrosion (a natural phenomenon) from occurring on common metals surfaces used in today%u2019s construction are also well known. The substrate materials selection, products design, preparation process, finishing materials, and application process as well as the climate conditions during finishing are all important considerations that can, and will affect the service life of any organic coating.
