| Abstract: | A simple and efficient method to evaluate the titanium dioxide for the paint was introduced. Alkyd resin and 5 kinds of titanium dioxide were used to prepare paints. The oil absorption of titanium dioxide, physical properties （ including the gloss and fineness ） of the paint, QUVA aging resistance, humid heat test and outdoor exposure test were conducted, and the best kind of titanium dioxide were chosen by the experimental results. |
