Also improves the hydrophobicity of the coating and humidity resistance. Synergistic when used with anti-corrosive pigments. Is effective at low concentrations. Is specially designed for use in powder coatings. It can be used with various types of powder resin formulations, for all types of metallic substrates including as an additive for concrete.
