Last April, a team of scientists from the Purdue University published a study on the development of the whitest white paint in the world. At least until then. However, the fact that his research showed that the paint was capable of reflecting a higher percentage of the light that fell on it could not be considered a record. For that, it had to be evaluated by the judges of the Guinness Book, who have finally reached a resolution: it will be part of the desired list from the 2022 edition.
And is not for less. The earlier whiter white paint, introduced a few months earlier, reflected a 95.5% of the light. It is a large percentage. However, this reaches up to 98.1%. Practically perfect.
But the best part is that it not only serves to show off that you have finally found the whitest target that bleach ads talk about. It is also a very effective tool for save energy and fight global warming. It may sound crazy, but it certainly isn’t.
The whitest white paint, finally in the Guinness Book
The previous white paint had been made from calcium carbonate particles suspended in an acrylic paint medium. The results were good, but something was missing.
This paint was made by playing with the size of the particles to make it less brittle
Therefore, for which now enters the Guinness Book of Records, they tried another substance: barium sulfate. It is a powerful whitening; therefore, the more quantity, the whiter the paint would be. The problem is that from a certain concentration the result became flaky and brittle when drying. You could not paint a surface well with it.
But they found a solution, since they saw that if they played with the particle sizeBy adding some larger than others, they were organized, giving rise to a smooth and homogeneous white paint, even after drying. And all this without losing its ability to reflect light.
This would save energy, since buildings painted with this white paint remain colder, by reflect sunlight. In fact, in some of the experiments that were carried out, they managed to cool a house more than some air conditioners, without the energy consumption or the negative consequences for the planet that these entail.
There are plenty of reasons to consider this white paint a great invention, which now also goes into the famous Guinness Book of Records. We can already say it with complete certainty: it is the whitest white paint.
