Part one of this article discusses the theory of optimizing applied hiding and new techniques used to characterize applied paint films to determine the influence of rheology on application.
A century after the first industrial production with the sulfate process and 60 years after the birth of the chloride process, the AT process brings a new facet to this industry.
The use of the pigment encapsulating acrylic binder in exterior applications can not only decrease the amount of TiO2 at the same hiding level, bringing possible cost reduction, but can also help to improve exterior durability such as dirt pick up resistance, tint retention and efflorescence resistance.
