Floor XZ-PG08 silica additives, the average diameter of 100nm particles filled voids in the refractory material and the concrete, improve the volume density and the porosity decreases, with the impact on seepage and wear parts. After the incorporation of silicon dioxide in concrete, it can greatly improve the impermeability, impact resistance, cavitation resistance, significantly improve the adhesion and cohesion of concrete, and extend the service life of buildings. Can also be used as paint, paint matting agent. Features: This product quality is stable, good dispersion, in the production of powder processing extinction performance is good; the extinction powder used in paints made after the extinction effect is good, high transparency; this product is made of matting agent in paint storage will not produce hard precipitation.
