World’s Whitest Paint can save your bills. It is an revolution in paint industry.

Xiulin Ruan, working as a Professor of Mechanical Engineering in Purdue University developed the Whitest Paint. Xiulin Ruan and his co-workers found that the paint’s whiteness means that the paint is the coolest on record. 

The researchers demonstrated outdoors that the paint can keep surfaces 19 degrees Fahrenheit cooler than their ambient surroundings at night by using high-accuracy temperature reading equipment called thermocouples. Also they found that it can cool surfaces 8 degrees Fahrenheit below their surroundings under strong sunlight during noon hours. 

During an outdoor test with an ambient temperature of 43 degrees Fahrenheit, the paint still managed to lower the sample temperature by 18 degrees Fahrenheit. The paint's solar reflectance is so effective that it even worked in the middle of winter.

In short, it was found that using barium sulfate absorbs up to 99.9% of visible light. The new whitest paint formulation reflects upto 98.1% of sunlight. It was compared with the 95.5% of sunlight reflected by the researchers’ previous ultra-white paint. The second feature is that the barium sulfate particles are all different sizes in the paint. 

The technology may benefit a wide range of industries, including residential and commercial buildings, data centers, warehouses, food storage, automobile, outdoor electrical equipment, military infrastructures, and utility vehicles. The paint may be applied directly to buildings to reduce cooling costs.

Telecommunication companies may use it to prevent outdoor equipment from overheating, an important step toward enabling a 5G network because the paint lacks metallic components.

The technology may benefit to fight against global warming. The paint has earned a Guinness World Records book for being so white. Moreover, the technology will be better than air conditioners for cooling residential and commercial buildings, data centers, warehouses, food storage, automobile, outdoor electrical equipment and utility vehicles.
