CELITE 281 SS BL is a medium particle size product of very high whiteness that can be used for flatting applications. CELITE 281 SS BL has a typical particle size distribution that retains 0.88% by weight on 325 mesh and has a diameter at which 10% is less than 7.9 um making it well suited for surface applications where smoothness and opacity is required. These key technical properties of CELITE 281 SS BL allow it to provide surface smoothness and uniform coverage in surface coating applications.
