How many grain sizes are used in coating mica powder?
With the development of coatings industry, the corresponding properties of the coating have higher requirements, sericite with its unique advantages in the paint industry is confirmed and application. Such as: building exterior wall coatings, antirust paint, coating, heat insulation, anti-corrosion coatings, anti fouling, anti radiation, aerospace thermal control coatings.
Antibacterial antivirus, coatings can never fade. In fact, 800 mesh and 1250 mesh mica powder differ in particle size, particle size is 800 mesh 1250 mesh 13um, mica powder particle size is about 10um, of course, this is only the average particle size, depends on the specific size distribution is not normal. Mica powder particle size distribution in Shenzhen Haiyang powder is normal, we have been using the mica powder. They also feel good.
For the characteristics of Sericite in the coating industry is: can improve coating UV blocking and moisture permeability, enhance coating weatherability, delay powder, to prevent cracking. Lamellar structure of sericite, can increase the cover rate of coating, reduce the amount of the pigment, the cost is low. Sericite easy dispersion, good suspension, not easy to precipitate attached, strong compatibility with other pigments and solvent, can enhance coating fullness, toughness, Naicaxi. Join mica coating, good chemical stability, heat resistance, acid resistance and has good electrical insulation,
