Abstract : Stripping agents for epoxy coatings were investigated for use in a Ship Tank and Bilge Chemical Cleaning Hardware and Processing System (STABCHAPS). This system recycles hot solutions for the removal of contaminants, rust, and coatings. Available commercial stripping agents did not prove to be satisfactory. A very effective stripping agent, NCEL Stripping AGent H4, was developed. It consists of 77% N-methylpyrrolidone, 22% ethanolamine, and 1% lgepal C0630. However, this stripping agent is too hazardous for general use and needs to be modified. (Author)
