Abstract
Inorganic binders for coatings such as paints are provided which are based on high single or mixed silicon dioxide to alkali metal oxide mol ratio inorganic alkali metal silicates. The binder composition comprises a mixed silicon dioxide silica gel sol having a silica to alkali metal oxide mol ratio of about 5.5-6.5:1. The binder composition is produced from a starter alkali metal silicate aqueous solution by mixing the solution with a silicone monomer and agitating until hydrolysis is essentially complete. A silica gel is then added as an aqueous slurry and blended until the silica gel is at least partially dissolved. Thereafter, the mixture is agitated to a smooth consistency and recovered as a binder composition. The inorganic binder is particularly suitable for providing coatings or paints having good brushability and which contain zinc dust or aluminum powder for application over ferrous substrates.
