The methods for creating energy efficient cool gray building coatings-Part II: Preparation from pigments of complementary colors and titanium dioxide rutile

摘要

The method to create cool gray coatings colored with mixtures of black and white pigments was described in a companion paper. In the current article, the method to prepare colorful cool gray coatings by mixing pairs of pigments of complementary colors and titanium dioxide rutile is introduced. The qualified cool light blue-gray and orange-gray coatings are created by mixing complementary cobalt aluminate blue and cromophtal yellow paste with the white coatings in appropriate proportions. The cool light to moderate yellow-gray and violet-gray coatings are formulated by blending complementary nickel titanate yellow and dioxazine purple paste and the white coatings in suitable proportions. The eligible cool light green-gray and red-gray coatings are colored with mixtures of complementary cobalt titanate green and irgazin red paste and the white coatings in appropriate proportions.
