Abstract
A composition based on a certain chromium-free silicate-based binder is described. The composition is an aqueous solution of lithium-doped potassium silicate in combination with an aluminum or aluminum alloy powder, zinc powder or a combination thereof. The coatings of the present invention are capable of achieving a full cure at temperatures as low as 350-450 degrees F. by the inclusion of a colloidal solution of a nano-sized ceria, thus making the coatings especially suitable for application on temperature sensitive base materials.
