Behr Has Obtained a Patent for Pigment Spacing

Behr Process Corporation has obtained a patent for a process for modifying a paint composition containing titanium dioxide particles comprised of dispersing between a 0.05%and a 5.0%by weight of metal oxide nanoparticles,pre-treated to minimize flocculation,in the paint composition containing the titanium dioxide particles;and interacting the metal oxide nanoparticles and the titanium dioxide particles to form an intervening dispersion of a plurality of metal oxide nanoparticles,the intervening dispersion uniformly distributed around the titanium dioxide particles;wherein the step of dispersing the metal oxide nanoparticles is comprised of mixing a first set of metal oxide nanoparticles having a first average particle size and a second set of metal oxide nanoparticles having a second average particle size,the first set of metal oxide nanoparticles and the second set of metal oxide nanoparticles having pre-treated surfaces to minimize flocculation;and further wherein the first average particle size is approximately 120 nm and the second average particle size is 60 nm.
