| 20090071372 | WATER-BASED COATING COMPOSITION AND HEAT-SHIELDING COATING - The problem to be solved by the present invention is to provide a thermal shielding coating exhibiting high thermal shielding properties. The water-based coating composition in accordance with the present invention is characterized by inorganic particles inclusive of spherical metal oxide particles being contained therein. Various chemical compounds, etc. are contained in the water-based coating composition, but by adding spherical metal oxide particles, it has become possible that the water-based coating composition exhibits high solar reflecting properties, as described before. Conventionally, the present inventors have developed inorganic particles exhibiting increased sphericities, and in the course of the development of the inorganic particles exhibiting increased sphericities, they have found that the inorganic particles exhibiting increased sphericities can be dispersed in liquid with very high concentrations, and have contemplated the application of the inorganic particles exhibiting increased sphericities to the coating composition. They have confirmed that the thermal shielding properties are also improved as the result of a large amount of inorganic particles which are excellent in solar reflecting properties being able to be contained in the coating composition, and have completed the present invention. | 03-19-2009 |
