Development of a Corrosion Control, Nonemissive Paint for the Protection of Bilge Spaces

摘要

A research program has been conducted to develop a corrosion control nonemissive paint for the protection of bilges. This report covers Year Two of a multiyear development program. Laboratory studies have been concerned with developing bilge paints based on water-dilutable resins (polyvinylidene chloride, neoprene, acrylic, and polyurethane latices), 100% solids epoxy resins, and cementitous resins. Several preliminary formulations based on epoxy and cementitious resins have been identified as bilge paint candidates. The effects of poor surface preparation as encountered on a submarine under way, particularly on paint adhesion, have also been studied. It appears that epoxy-resin based paints may be sufficiently forgiving to accept these limitations without compromising performance. Long-term paint adhesion has yet to be determined. (Author)
