Patent ID: 7304021

Claim:
A method for manufacturing a paint removal formulation having a color change feature, said method comprising: combining at least one penetrant, at least one water insoluble carrier and at least one color visible colorant to form a formulation, said penetrant is selected from a 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 naphtha and mixtures thereof, and said water insoluble carrier is selected from a 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, wherein said carrier is in a sufficient quantity to perform said color change feature, and whereby said formulation is designed to be applied to a target area and as the surface of said formulation dries, said colorant migrates away from a surface of said formulation thereby creating a color change to indicate that said formulation with the stripped paint is ready for removal.
