•  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
