The material is designed to penetrate the crevices to which it is applied. The steel may have been treated with various phosphates, production primers, sealers, and topcoats. Compatibility with each of these substrates in a variety of conditions must not affect the corrosion inhibiting properties of the anticorrosion coating. It will usually be applied in the post oven areas of normal paint operations. It shall be homogeneous, free of chlorinated solvent. asphalt, or fibrous filler such as asbestos. It shall dry to a permanently soft coating without sagging or refluxing upon itself. The visibility of the material is enhanced by blacklight.
