Course Description
It is now, during these times of short TiO2 supply, more important than ever to use TiO2 as effectively as possible.  The course will cover the basics of light scattering (white opacity), techniques for measuring opacity and determining the opacity efficiency of TiO2 used in paints, and the benefits and limitations of using alternative technologies or strategies for opacity.
Learning Objectives

  • Understand the factors that influence light scattering by a particle
  • Understand how light scattering from individual particles scales up to total opacity of a film
  • Understand methods for measuring opacity and determining the efficiency of TiO2 light scattering in a paint
  • Understand the benefits and limitations of using alternative technologies to enhance / maximize paint hiding:
    1. Response of total hiding to TiO2 loading
    2. Effect of replacement of TiO2 or other particles by spacer particles
    3. Opacity from entrapped air
    4. Opacity increase from improved dispersion of white pigment
    5. Deriving opacity from light absorption as an alternative to white hiding.

Course Instructor
Dr. Michael Diebold is an inorganic chemist by training, having received his BS degree from the University of Illinois and his PhD from Texas A&M University.  Mike is currently a Research Fellow in DuPont Titanium Technologies, where he has worked for the past 22 years.  His primary responsibilities including plant support, customer support and new TiO2 product development.  He holds 5 patents and is author or co-author of over 40 papers in a variety of fields.  His honors include an NSF pre-doctoral fellowship, a NATO post-doctoral fellowship and, in the coatings field, both a Stern Award and a Roon Award.  He gave the Technical Focus Lecture at the 2003 ICE show, a plenary lecture at the 2005 International Coatings Congress in Nuremburg, and has been an FSCT Distinguished Lecturer.
