nano calcium carbonate for print ink

CC-OT series for print ink (Nano precipitated calcium carbonate for print ink)

CC-OT a nano-structured calcium carbonate exclusively used for high standard printing ink,is tasteless white powder upon surface treatment,The particle diameter is 20-50nm,and shape of the crystal is ‘cubic’ is has the following advantages:good dispersing ability ,high surface activeness and regular particles.

1) Applicable characteristics: it is easily dispersed in printing ink with proper friction resistance,it is able to adjust the color concentration,denseness of printing ink and other physical features so that the printing ink is well printable,rhelogic,adhesive and covering with brightness and lightness increased.

2)Applicable scope: All type of medium to high standard printing ink

3)Packing: 25KG paper plastic composition bag

4)Storage: we recommend storing CC-OT in the dry and ventiated places
