CoatingsTech Mattiello Lecture
“Optimizing the Benefits of TiO2 in Paints”

Dr. Michael Diebold, technical fellow, R&D, at Chemours Company, will deliver the Mattiello Lecture at the 2019 CoatingsTech Conference on Tuesday, April 9.

In his address, titled “Optimizing the Benefits of TiO2 in Paints ,” Diebold will focus on the formulation factors that affect the light scattering efficiency and the durability performance of TiO2, and techniques to optimize these properties.

TiO2 is found in virtually every coatings lab and manufacturing site around the world and is used in almost all paints. The primary role of TiO2 is to provide brightness and opacity, with a secondary role in many exterior paints of improving durability. The effectiveness of TiO2 as a brightener or opacifier is greatly affected by the specifics of the paint formulation and by the paint making process. This sensitivity can be understood in terms of the physics that govern light scattering. For improving paint durability, TiO2 is an excellent UV light absorber and protects underlying resin from harmful UV radiation. However, this benefit can be offset by the formation of radicals at the TiO2/resin interface.

For his lecture, Diebold will receive the Joseph J. Mattiello Lecture Award, which recognizes an individual who has made outstanding contributions to science, technology, and/or engineering related to the coatings industry. Joseph J. Mattiello, whose memory is commemorated by this award, did much to expand the application of science in the decorative and protective coatings field.
