The depainting effect of the paint remover is achieved through a series of physical and chemical processes such as dissolution, penetration, swelling, stripping and reaction. There are various types of paint removers abroad, and in terms of organic paint removers, there are mainly trialkanes, methyl-2-pyrrolidone ketones, halogenated hydrocarbons, y-butyrate esters, organic acids, etc. Trialkane paint removers can only remove alkyd paint, polyurethime paint, etc; N-methyl-2-pyrrolidone paint remover can remove acrylic paint and polyurethime paint; Halogenated hydrocarbon paint remover can remove epoxy paint, amino paint, alkyd paint, acrylic paint, polyurethime paint, etc., and the required time is 5min-2h; Y-Butadiene white ester and organic acid paint remover can remove two-component epoxy paint and polyurethime paint; Organic acid paint removers can remove architectural coatings.
