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