Construction glass flake coating anti-corrosion coating anti-corrosion coating main function is to make the corrosive medium and the substrate to be coated isolation, so corrosive media difficult to penetrate to the base surface. Proportional to the square life of the coating and the coating thickness, coating thickness increases, the time may be extended to penetrate into dielectric substrate, the coating to extend the service life. Glass flake is a multi-parallel arrangement with the substrate, so that the spread of the media becomes a winding route, extending the media penetration and diffusion into the matrix of the journey, played a role equivalent to an increase of the coating thickness. By steam penetration test proved glass flake epoxy coating is equivalent to 0.1 mm thick coating 0.7㎜ thick. Third, glass flake epoxy coating species altogether seven kinds of glass flake paint, according to formula composition is divided into: colored glass flake epoxy paint and black coal tar epoxy glass flake paint; also in terms of solid content is divided into: Mastic Two-component glass flake paint and solvent-free three-component glass flake coatings.
