HOLLOW SILICA MICROPARTICLE, COMPOSITION FOR TRANSPARENT COATING FORMATION CONTAINING THE SAME, AND SUBSTRATE WITH TRANSPARENT COATING

Hollow silica microparticles suppress whitening of a transparent coating film and show excellent abrasion resistance and adhesiveness. The microparticles having the average particle diameter of 5 to 300 nm and the specific surface area of 50 to 1500 m 2 /g, and also having an outer shell in which ca...

Zusammenfassung:	Hollow silica microparticles suppress whitening of a transparent coating film and show excellent abrasion resistance and adhesiveness. The microparticles having the average particle diameter of 5 to 300 nm and the specific surface area of 50 to 1500 m 2 /g, and also having an outer shell in which cavities are formed. The microparticles lose the weight by 1.0 W% or more at a temperature range from 200 °C to 500 °C when measured by the thermogravimetry (TG), and the microparticles have a positive DTA peak at the temperature range when measured by the differential thermogravimetric analysis (DTA).
