Patent ID: 10406505

Abstract:
The present invention provides a coating composition suitable for use in forming a coating that can reduce a concentration of pollutant gases in the environment. The coating composition includes from 0.01 to 10 vol.-% of mesoporous titania particles, relative to a total volume of the coating composition, and from 5 to 99.99 vol.-% of a polymeric material, relative to the total volume of the coating composition. The mesoporous titania particles have a continuous exterior convex surface, a particle diameter of ≥1 μm but ≤ to 50 μm, a BET specific surface area of from 30 to 350 m2/g, a modal pore diameter of ≥5 nm but ≤50 nm, and a pore size distribution so that 85% or more of a total pore volume is associated with pores having a diameter of 10 μm or less.
