HAKUENKA O is a superior ultra-fine calcium carbonate coated with an organic compound. It has 30 nm uniformed ultra-fine particles as the primary particle. These particles are surface-treated with rosin acid in order to provide compatible surface modification when it is mixed with organic materials or with vehicles.
Common Applications: HAKUENKA O is mainly used for ink applications as an extender pigment for better transparency and gloss. It is also ideal for the rubber industry. Rubber compounds with HAKUENKA O show better tensile strength, tear strength and flex resistance.
Type: Precipitated Calcium Carbonate
