[PROBLEMS] To penetrate ultraviolet rays and infrared rays of sunlight from the glass surfaces of buildings, car windows, etc., and raise the internal temperature of the inside of the room and the inside of the car, etc., and also cause sunburn of the human body and deterioration / damage of products and exhibits due to ultraviolet rays. Therefore, there is a strong demand for this preventive measure. As this measure, a coating agent having an infrared absorption and shielding function intended to be applied to the glass surface is provided. As an infrared absorbing agent, tin oxide, zinc oxide, indium oxide is doped with a different metal, an inorganic pigment is used as a main agent, an inorganic coloring pigment is blended as an infrared absorbing auxiliary agent, and an inorganic binder is further added. By adding a curing accelerator and a drying rate modifier to the mixed solution with the alkoxysilane compound added, it can be easily applied to the glass surface and has excellent durability and pot life. Coating agent with excellent infrared absorption and shielding function. [Selection figure] None |
