It's not visibly reflective. Yes, it's white, but it's cool to the touch because the majority of the energy is radiated out into space via non-visible wavelengths. Someone has already posted a great YouTube video from Night Hawk In Light in a comment where he explains how this tech works and makes his own paint!

Yeah, it's good to read the article before commenting.

Here's a link to the Night Hawk video. Good stuff. https://invidious.fdn.fr/watch?v=KDRnEm-B3AI This guy just gives away a formula he developed for the pigment. OG shit.
