Abstract

A high-hardness clear coating material capable of improving hardness and corrosion resistance of an aluminum material surface includes, in % by weight, 10 to 20% of a melamine curing agent, 10 to 15% of silica, 1 to 5% of a phenol resin, and a remainder of an acrylic resin and other unavoidable impurities.

First claim

What is claimed is:

1. A high-hardness clear coating material capable of improving hardness and corrosion resistance of an aluminum material surface, the material comprising in % by weight of the material:
10% to 20% of a melamine curing agent;
10% to 15% of silica;
1% to 5% of a phenol resin; and
a remainder of an acrylic resin and other unavoidable impurities.

2. The high-hardness clear coating material of claim 1 , further comprising in % by weight of the material:
10% to 15% of a cyclohexanone solvent;
5% to 10% of an aromatic solvent; and
1% to 5% of a pulverized silica matting agent,
wherein the content of the acrylic resin is from 40% to 50%.
