Lofty paint remover of the new project can produce synergistic effect with the main solvent to increase the engineering paint remover in the organic coating in the diffusion rate, improve the film swelling, wrinkling capacity, thereby improving the stripping efficiency. In order to effectively control the corrosion degree of tinplate, two kinds of alkaline solvents, such as lactic acid, citric acid, ethylenediamine and ethanolamine, which are of low acidity are selected as the accelerator of engineering paint remover. The other components remained constant at a constant temperature of 60 ° C.
