The adhesion to steel of polyurethane coatings with titanium dioxide fillers was examined using a roller adhesiometer. It was found that adding the filler increased the hardness of the resin and its adhesion. Adhesion was also found to vary with the proportion of isocyanate to hydroxide in the resin, and increasing temperature caused a decrease in adhesion. Adhesion calculated from a mathematical model agreed with the experimental data. It was concluded that the equations obtained from the model could be used in the solution of practical problems concerned with adhesion.
