Sol-gel Process Print E-mail

The sol-gel process, invented in the mid-80s, is an important part of many nanochemical processes. It involves a solution (sol) that is dispersed evenly throughout a gel of active molecules which form a network after the solution or solvent is removed or has evaporated.


The Ultraclean Glass ™ / Porcelain™ CONVERTER chemical, once applied, triggers a multi-stage process with bonding and repellent components forming a network after the solvent (denatured alcohol) has evaporated. In detail, the process looks like this:



The coating system is applied to the surface.
The solvent evaporates.


A first organization takes place where the silicon-containing bonding component (blue dots in the diagram) bonds covalently with the surface and cross-links with neighbouring molecules to form a strong three-dimensional matrix.


During the curing, the compounds organise themselves in a nano-scale monolayer. The fluorine-containing repellent component (red dots in the diagram) on top makes the glass hydrophobic and oleophobic.
