Coating composition for preventing adhesion of advertising material and method for coating by thereof

A coating method for inhibiting adhesion of unwanted materials, comprising the steps of:

• coating and drying a first coating composition on an installation;
• and coating and drying a second coating composition on the coating layer formed with the dried first coating composition, wherein the first coating composition comprises:
• 25 to 35 parts by weight of urethane resin solution, acrylic resin solution, or epoxy resin solution,
• 5 to 35 parts by weight of urethane pigment, acrylic pigment, or epoxy pigment,
• 10 to 20 parts by weight of PE-thermoplastic resin beads, phenol resin beads, melamine resin beads, epoxy resin beads, polystyrene resin beads or glass beads,
• 40 to 52 parts by weight of urethane thinner and toluene, and
• 2 to 4 parts by weight of curing agent, and
• particles of luminous paint comprising 10 to 15 unit weight per 100 unit weight of the first coating composition, the particles of luminous paint having diameters between 50 and 250 μm,
• wherein the coating layer, on drying, has small irregularities on the dried surface, resulting in improved visibility and improved releasability of unwanted materials;
• and
• wherein the second coating composition comprises:
• 8 to 12 parts by weight of silicone release agent,
• 40 to 55 parts by weight of hexane,
• 20 to 25 parts by weight of toluene, and
• 0.08 to 0.18 parts by weight of platinum catalyst.
