Inorganic Coatings
The binder of inorganic coatings is not based on organic polymers (e.g., acrylic, polyurethane) but on naturally occurring silicates (e.g., potassium silicate, silica sol). The film-forming mechanism involves a chemical bonding reaction with mineral substrates (e.g., concrete, plaster), forming a stable —Si—O—Si— network structure.
