Description

In the paper manufacture industry, precipitated calcium carbonate (PCC) and titanium dioxide (TiO2) have been widely used as a filler in order to improve whiteness and opacity of paper for many years. TiO2 is an expensive product and has a problem, which is low one-pass retention in paper making process compared with PCC.<br>Recently, the composite of TiO2 and PCC has been researched by various methods in order to improve retention and optical properties such as opacity and brightness. “Valkofil” is our new Pigment combined with TiO2 and PCC using our unique process. Valkofil is able to give higher opacity and Light Scattering coefficient (L. S. C) to paper than conventional PCC.
