Surfactants and Defoamers in Waterborne Coatings


This lecture discussion the use of surfactants and defoamers in waterborne coatings.  The objective is to provide an understanding of the factors that influence surfactant and defoamer selection and performance in coatings.  The course starts with a basic introduction to surface chemistry.  It continues with a discussion of what surfactants and defoamers are and how they work.  The focus is on explaining ways to select surfactants and defoamers to avoid defects and obtain optimal coating performance
