AbstractNo evidence was found for weak boundary layer formation when the adhesion of polystyrene lacquer to various high surface tension substrates was measured, using a spontaneous peeling method. The results showed a considerable variation from one substrate to another, and the interfacial work of adhesion seems to be related to the dispersion component of the substrate surface tension. Correlation was found between polystyrene adhesion to and the wetting of the substrates by organic liquids. It was confined to those governed solely by dispersion forces, as is polystyrene. Results for the critical surface tension of the substrates indicate that their wetting behaviour is dominated by an adsorbed surface layer of water. This layer does not, however, seem to influence the adhesion of the polystyrene coating.
