Abstract
Excellent adhesion of vitreous enamel to steel can be achieved via an intermediate layer formed on the steel by bringing it into contact with a liquid composition that contains water and a component of solute selected from the group consisting of dissolved silicates and dissolved borates and, optionally, surfactant. The modification of the steel surface achieved by treating it with silicates and/or borates is also effective for improving the adhesion of steel to other protective type coatings such as paint.
