- SiO2 – 68-70 %
- Bulk density: from 0,12 g/cm3
Glass microspheres are made of soda lime boric glass. They are in the form of white, free-flowing powder, made of perfectly smooth, spherical particles. Glass microspheres are the filler with increased durability and low density, reducing weight of the finished product up to 30% without the quality losses. Properties of the microspheres reduce considerably the shrinkage of coating while drying, improve their smoothness, flow ability and wettability. Glass microspheres are used as thermal insulator in paints and plasters.
Average available sizes (µm): 10 – 125.
