  • Publication number: 20130059148
    Abstract: A solar heat shielding coating solution is disclosed. The solar heat shielding coating solution comprises a sol-gel organic-inorganic composite binder solution and a nanosized metal oxide ink. The sol-gel organic-inorganic composite binder solution includes a sol-gel organic-inorganic composite resin, which is composed of a mixture of an acrylic polymer resin and a sol-gel silicate as an inorganic ceramic, and a solvent. The nanosized metal oxide ink includes a nanosized metal oxide, a dispersant capable of effectively dispersing the nanosized metal oxide, and a solvent. The coating solution can be coated to a small thickness on glass while maintaining transparency. In addition, the coating solution has high visible light transmittance, infrared light blocking rate and hardness, and exhibits good weather resistance, solvent resistance and adhesiveness.
