VAPORLITETM SL 90 T is a ultra fine sub-micron calcium carbonate.The sub-micron particles of VAPORLITETM SL 90 T can act as a spacers between TiO2 particles leading to increased the efficient separation at TiO2 in the paints and coating application.
The size and numbers of VAPORLITETM SL 90 T particles enable efficient separation at TiO2 particles and inhibit re-agglomeration after dispersion whereas agglomerates are less efficient at scattering light when compared to the fine primary particles. As light beams are refracted at the particle surface it follows that smaller and more numerous fine particles offer more opportunities for refraction and thus lead to better coating OPACITY and HIGHGLOSS. |
