Ship Bottom Paint Systems - I - The Role of Fatty Acids and Soaps in the Adhesion of Underwater Primer
Abstract
Recent experience with systems for the protection of underwater surfaces of ships has indicated poor performance due to loss of adhesion. This report describes an investigation of the primers designed for direct application to steel over which anti-fouling paints are applied. A number of primers were prepared in which the pigment-volume ratio was varied as well as the type of pigment. The composition of the primer matrix was varied between wide limits. Exposures were made of each system for periods up to seven months. The data indicate the preference for zinc oxide over zinc chromate as an underwater primer pigment for steel.
