The internal structure of glass flakes is very similar to that of glass fibers, which are produced by rapidly cooling molten glass under tensile force. Below the melting point, it is generally in a stable equilibrium state with the lowest thermodynamic free energy. So the performance of glass flakes is different from that of gradually cooled flat glass, as their strength is much greater than that of ordinary glass sheets. If glass flakes are used as a coating filler for anti-corrosion protection, it will also have superior performance compared to fillers such as mica, calcium silicate, and aluminum silicate.

Due to the overlapping arrangement of glass flakes in the coating, they play a significant role in the anti permeability of the coating film. The coating method can be brush coating, high-pressure airless spraying, or roller coating.
