  • Patent number: 6756123
    Abstract: Disclosed is an anticorrosion paint for preventing steel materials from corrosion by using polyaniline as an anticorrosion pigment. The anticorrosion paint has an excellent anticorrosion effect, long persistence of the anticorrosion effect, high durability and superior coating property controlling the anticorrosion effect, without using metal causing environmental pollution as an anticorrosion pigment. Especially, in the anticorrosion paint, the top coat paint for improving the protection of the primer coat paint and the anticorrosion effect. The top coat paint includes 40 to 89 wt % of matrix resin, 5 to 54 wt % of colored pigment, 1 to 50 wt % of dopants and 5 to 54 wt % of mixed solvents, and the primer coat paint includes 3 to 49 wt % of the polyaniline, 40 to 86 wt % of the matrix resin, 1 to 47 wt % of the dopants and 10 to 56 wt % of the mixed solvents. The anticorrosion paint plays a role in exerting persistently the excellent anticorrosion effect without causing environmental problem.

  • Patent number: 6355707
    Abstract: Disclosed is an electromagnetic wave-shielding coating material which is superior in both paintability and a electromagnetic wave shielding activity. Also, the coating material is of antistatic activity. The coating material comprises polyaniline (ES) with a solid content of 1-50%, a matrix polymer with a solid content of 1-50%, and additives at a predetermined amount. Also disclosed is an electromagnetic wave-shielding coating material, which is prepared by mixing polyaniline (ES, 100%), an acrylic resin and additives at predetermined amounts and adding the mixture with a hardener and a mixed solvent at predetermined amounts just before use. The electromagnetic-shielding coating material is able to effectively shield electromagnetic waves with a broad band of frequencies and be coated onto cases of various electromagnetic apparatuses, thereby protecting the body from electromagnetic wave pollutions.
