• ultra-light weight filler • soda-lime borosilicate glass microspheres • non porous , better stability at reduced cost • round shape , improved workability • light weight , lower viscosity • whiteness • improved abrasion resistance , better sanding • reduce shrinkage • chemically stable , water resistant • low thermal conductivity

glass microspheres do can break and lose their effect: • Prevent intensive high shear mixing • preferred planetary mixing system • low speed dispersion • add filler slowly at last stage of production • first half after that step-by-step
