The variation in particle size of mineral pigments leads to differences in hiding power, primarily attributed to the phenomenon of light scattering. This phenomenon contributes to smoother color ...

Dynamic Light Scattering is commonly used to rapidly measure the hydrodynamic size and size dispersity of nanoparticles in suspension. Several commercial DLS instruments exist, using a range of ...

How do particle size and shape affect the hiding power and color strength of inks, paints, and coatings? Dr. Beverly Barnum: Hiding power, or opacity, refers to the covering ability of a coating.

I am Dr. Beverly Barnum, a senior application scientist at Bettersize Instruments. I earned my Bachelor of Science degree in chemistry from California State University and later completed a Ph.D. in ...
