  • Patent number: 9068085
    Abstract: A radiation-curable base resin composition and a fingerprint-resistant resin composition including the same are provided. The radiation-curable base resin composition includes a multifunctional urethane(meth)acrylate having three or more functional groups at 3 to 35 parts by weight, a bifunctional urethane(meth)acrylate at 3 to 35 parts by weight, at least one (meth)acrylic acid ester monomer selected from a monofunctional (meth)acrylic acid ester monomer and a multifunctional (meth)acrylic acid ester monomer at 20 to 60 parts by weight and a radiation polymerization initiator at 0.1 to 15 parts by weight.
    Type: Grant
    Filed: October 16, 2009
    Date of Patent: June 30, 2015

  • 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.
