"Developed over decades by research scientist and chemist Ghostshield’s formulas are the most innovative concrete sealers available in the market. Utilizing molecular nanotechnology, the active ingredients are engineered to have the smallest atomic structures possible. The active particle sizes are 0.3 to 1.5 nanometers in diameter 100 times smaller than traditional chemistries resulting in deeper penetration, longer service life and unrivaled performance." -Retrieved 9/14/2020 from https://ghostshield.com/nano-technology
