PRELIMINARY SELECTION OF COMPATIBLE SOLVENTS FOR VINYL PAINTS

The Corps of Engineers uses two types of vinyl coatings extensively to protect immersed steel in inland waterways: one meets restrictive air pollution regulations and the other uses a vinyl zinc primer to extend coating life. This study examined alternate solvent systems which would meet the requirements of the air pollution regulations and would be compatible with the vinyl zinc primer. A solvent combination of methyl propyl ketone (MPK), methyl amyl ketone (MAK), and toluene in a vinyl formulation was used. The viscosity, water permeability, tensile strength, and retained solvents of this new formulation were compared with existing vinyl formulations. It was concluded that although the new formulation has properties very similar to the existing formulations, the MAK must be stablilized for the coating to have an acceptable shelf life. (Author)
