1, Colloidal silica is not just used in the production of paper, it is used either alone or with other components to improve paper's frictional and printing properties for board stock and inkjet/photo paper.
2,The non-slip surface created by colloidal silica can increase the slide angles of board and paper for easier processing and stacking. This can result in faster line speeds and easier handling of the finished product.
3,The creation of a pourous coating that readily accepts water based inks is a benifit for not only inkjet and photo applications, but also for packaging. Printed images are crisp and clear helping to upgrade the look of your packaging material.
