• composition containing the surface-treated calcium carbonate of the present invention is very excellent in storage stability, thixotropy and slump resistance.
• the surface-treated calcium carbonate of the present invention is used in a moisture-curable composition by using it together with a surface-treated calcium carbonate conventionally used in a moisture-curable composition. It can be seen that the disadvantage of long curing time, which was a disadvantage of surface-treated carbonated rubber, can be improved and shortened.
