Abstract:

The study led to the conclusion that the effectiveness of a paint stripper did not depend primarily on the paint polymer swelling abilities of the component organic solvents. It appears that some other parameters, for example, evolution of hydrogen in the case of Turco-5469, have to come into play before the solvents in the paint remover can effectively swell the paint polymer thereby causing the stripping of linear polyurethane paint systems. Furthermore, from the scanning electron micrographs it is surmised that there are enough pinholes and voids on the paint surface to enable the penetration and permeation of the common organic solvents.
