The nano-TiO_2 power is dispersed into traditional exterior wall coatings by surface-active agent
super shear instruments and ultrasonic dispersions
the properties of the coatings are studied.The experiments show that the overall properties of the coatings are evidently improved with addition of 0.5%wt dispersed nano-TiO_2 powders.This paper discussed the suitable dosage of nano-TiO_2 and its adaptability to the latex.
