Abstract
Coating compositions and methods for using the same are disclosed. The coating compositions can include an aminosilica adsorbent. The coating compositions can adsorb CO2.
Claims20
A method of passively controlling CO2 in an enclosed environment, comprising:
- applying to a surface in an enclosed environment an aminosilica-containing coating composition comprising:
- an aminosilica adsorbent;
- and
- a latex mixture, the latex mixture comprising one or more polyacrylic-based binders,
- wherein the aminosilica adsorbent is present at a volume that is within 20% of a volume of the one or more polyacrylic-based binders, and
- wherein the coating composition exhibits an adsorption capacity of from 0.2 mmol/g at 800 ppm of CO2 and 15% relative humidity to 1.5 mmol/g at 800 ppm of CO2 and 15% relative humidity, as determined according to a CO2 Adsorption Chamber Test.
