Résumé : |
Paint application by high speed electrostatic minibell spraying has become a common technique for industrial finishing and the standard method for Automotive OEM finishing. This report describes the findings of work carried out by SCM Chemicals using a solvent-borne single-coat automotive topcoat applied by this method. A major feature of this work has been the development of a quantitative instrumental method for the measurement of opacity. This method has been used to study the effects of pigment types and loadings. It is shown that by changing TiO2 products it is possible to influence the potential opacity of a paint and, therefore, the area that may be covered at complete hiding by a given volume of that paint. The effects on gloss and haze of the resulting paint films have also been studied. In the polyester/melamine system tested, zirconia treated products and particularly TiONA® RCL-628 have been shown to generate higher opacity than those based on current silica treatment technology. It has also been shown that the superior gloss and haze performance of zirconia treated products allows the use of lower film weights and/or higher PVC levels without incurring a gloss/haze penalty compared to the performance of silica treated products. |
