Abstract
The present invention relates generally to silicate-based coatings and to methods to make and apply same. In one embodiment, the silicate-coatings of the present invention are formed from a two part mixture of phosphate-based component and a glass-based component. In another embodiment, the silicate-based coatings of the present invention are free from any organic materials.
