Effective Utilization of Titanium Dioxide

چکیده
For example, if Coating A has a contrast ratio of 0.920 and Coating B has a contrast ratio of 0.900, about all that can be said is Coating A has higher opacity than Coating B. We can say it is 0.020 higher, but it is not clear how to use this number to formulate Coating B to have equal hiding. Also, this is not helpful in deciding what to change in order to improve opacity. Fortunately, quantitative answers to the questions above can be obtained with a reasonable amount of lab work using the equations of Kubelka and Munk. This approach is familiar to many workers in the field. We feel that using this technique is greatly facilitated by our user-friendly computer program. This paper will be devoted to explaining such a method and providing examples of how it can be used.
