Abstract:
1. A method of manufacturing a paint removal composition with a color change feature, said method comprising: admixing at least one penetrant, at least one water insoluble carrier, and at least one color visible colorant, prior to admixing, selecting at least one penetrant from the group consisting of NMP, benzyl alcohol, ethyl lactate, diethyl adipate, diethyl glutarate, ethyl benzoate, dimethyl succinate, diethyl succinate, dimethyl phthalate, diethyl phthalate, dimethyl terphthalate, diethyl terphthalate, ethylene bis(lactate), dimethyl sulfoxide, soy solvents, D-limonene, methylene chloride, toluene, methyl ethyl ketone, acetone, methanol, xylenes, mineral spirits, hi-flash naptha, dimethyl adipate, dimethyl glutarate, dimethyl succinate, butyl alcohol, ethyl alcohol, isopropyl alcohol, tertiary butyl alcohol, methyl alcohol, di-iso butyl ketone, methyl amyl ketone, butyl acetate, tertiary butyl acetate, isobutyl iso-butyrate, diethyl ether, ethylene glycol methyl ether, ethylene glycol butyl ether, turpentine, aromatic hydrocarbon, cyclohexanone, isophrone, heptane, hexane, kerosene, lacquer diluents, rubber solvent, benzene, chlorobenzene, cyclohexanol, monoethanolamine and mixtures thereof, and said carrier is selected from the group consisting of polysaccharides, starch, cellulose, polydextran, chitosan, chitin, limestone, metal oxides, aluminum silicates, hydrated aluminates, sodium magnesium silicates, barium sulphates, ferroxides, magnesium aluminum silicates and mixtures thereof, and creating a color changing paint stripper composition whereby said stripper composition is designed to be applied to a target area and said stripper composition changes from a visibly distinct color to a shade of white when said stripper composition with stripped paint is ready for scraping and removal.
