Abstract
An air purifying coating system and method for making same having a carrier agent and a diatomic frustule titanium dioxide particle dispersion combined with the carrier agent. The coating system may include 70-99.9 weight percent carrier agent and 0.1-30 weight percent diatomic frustule titanium dioxide particle dispersion. The carrier agent of the coating system may include a cleaning agent or a polishing agent. The diatomic frustule titanium dioxide particle dispersion may include 1-35 micron particle size diatomic frustule titanium dioxide particles combined with water and dispersion additive. The dispersion may further include an anti-settling additive, a rheology additive, and/or a defoamer.
