SiO2 Ultra Thin Coatings Use Natural Materials to Mimic Nature

Posted by:

SiO2 International Inc. uses natural silicon dioxide in their SiO2 technology to make superhydrophobic coatings just like nature does. SiO2 coatings form a surface structure similar to natural surface structures thus repelling water like many plants leaves, insects and animals.

Superhydrophobicity and self-cleaning properties pick up dirt particles by water droplets due to the micro- and nanoscopic architecture on the surface, which minimizes the droplet’s adhesion to that surface. This self-cleaning effect is of great importance as a protection against pathogens such as viruses, bacteria, molds, etc.

Due to high surface tension, water droplets tend to minimize their surface by trying to achieve a spherical shape (superhydrophobic).
