Great use of quartz sand powder!
quartz sand powder for coating and painting High purity quartz sand powder has special optical properties that conventional SiO2 does not have. It has strong ultraviolet absorption and infrared reflection characteristics. The addition of silica powder to the coating can form a shielding effect on the coating, achieve the purpose of anti ultraviolet aging and thermal aging, and increase the thermal insulation of the coating. The hardness and adhesion of the UV curable coating are improved and the absorption of UV radiation is weakened by doping high-purity silicon powder into the UV curable coating. Thus, the curing speed of UV curable coating is reduced. High purity silica powder has a large specific surface area, shows great activity, and can form a network structure when the coating is dry. At the same time, the strength and finish of the coating are increased, the suspension of the pigment is improved, and the color of the coating can be kept unchanged for a long time. The amo
