About Ceracool RadiaTIVe Cooling Paint
How It Works
Ceracool's Radiative Cooling Paint offers free air conditioning by reflecting over 95% of solar irradiance and simultaneously emitting heat into the near-absolute-zero temperatures of deep space through the atmospheric transparency window.
Ceracool paints can be conveniently sprayed or brushed onto a variety of surfaces such as roofs, roads, heat exchangers, and cold transport containers, with application possible both in a factory setting and on-site.
Cool roofs result in reduced need for air conditioning in buildings, decreased urban heat, and contribute to a cooler planet overall.
The Whitest White, and Colors, Too
Ceracool white paints boast solar reflectance of up to 99% and emissivity of 97% within the atmospheric transparency window. Meanwhile, our colored paints reach solar reflectance levels of up to 96% and emissivity of 95%.
Ceracool colored paints not only enhance the visual appeal of radiative cooling technology but also deliver superior performance.
For instance, conventional two-coat acrylic white paint, with an 85% solar reflectance, absorbs twice as much solar energy compared to Ceracool's red paint, which has a remarkable 93% solar reflectance. In contrast, standard red paint typically offers a mere 17% solar reflectance, according to LBNL.
Durability of Ceramics
Achieve 30+ year durability in just two coats.
Ceracool's base coat delivers vivid color, robust mechanical strength, and secure adhesion to surfaces, along with outstanding solar reflectivity and emissivity. The top coat offers enduring all-weather protection and low-maintenance cleanliness for over three decades.
Saving Lives, Mitigating Global Warming
As temperatures climb, wet bulb readings reach dangerous levels for vulnerable groups, especially the very young and elderly in regions with limited air conditioning access. Ceracool Radiative Cooling Paint is an economical solution to cool individuals, urban areas, and the planet. It can lower indoor temperatures by 3-10 degrees Celsius, a crucial difference that can save lives during heatwaves.
The Urban Heat Island effect poses a significant challenge in cities globally. Traditional air conditioners expel heat from buildings back into the urban environment. In contrast, Ceracool Radiative Cooling Paints not only dissipate this heat into the atmosphere but can also cool other urban structures, including sidewalks and roads. This makes cities more livable, particularly benefiting economically disadvantaged communities who often reside in areas with darker surfaces and have limited air conditioning access.
Minimizing the use and intensity of air conditioning conserves energy and consequently decreases carbon dioxide emissions from power production.
Created at the University of Maryland
Professor Liangbing Hu leads the world-renowned Materials Innovation and Manufacturing Group at UMD. Working with Research Scientist Dr. Xinpeng Zhao, the team developed the world's first a ceramic-based radiative cooling paint formula.
Read the paper in Science about Generation 1: ultra-thin heat-sealed coating.
Our newer Generation 2 is a thin coating that cures at ambient temperature.
The intellectual property for ceramic radiative cooling paint is licensed exclusively to Ceracool for unlimited fields worldwide. Ceracool's technology is patent pending.
