Ultrawhite Barium Sulfate (BaSO4) Subambient Radiative Cooling Paint via High-Shear Emulsion Dispersion
Cleared
This concept cleared all seven gates and every voiding sub-test.
| Incumbent displaced | Henry 887 Tropi-Cool 100% Silicone White Roof Coating |
| Measured advantage | Provides a categorical capability (+117 W/m2 peak daytime sub-ambient cooling power, cooling surfaces >4.5°C below ambient) compared to incumbent Henry 887 Tropi-Cool, which cannot achieve sub-ambient cooling due to TiO2 UV absorption. |
| Time to first revenue | 4 months |
| Gross margin at parity | 97.2% |
| Startup CapEx | $5,000 |
