As one of the market leaders in the field of paper chemicals, Clariant has been involved in paper coating and in enhancing the surface of paper for many years. Following market trends, the company also remains consistently true to its commitment to deliver specialty products to the paper industry.
The wide range of Cartacoat B coating binders includes synthetic emulsion polymers used for the production of various special paper grades.
More recently, Clariant has been focusing on Cartabond® crosslinkers. In addition to traditional glyoxal resins, the company has been developing zirconium salts with capability to cross-link with all carboxylated binders.
Cartabond surface strength improvers deliver cost improvements and improved productivity through faster machine speeds, savings in energy due to improved drainage along with improved mechanical properties.
Cartaseal® barrier coating additives are another key component in the Clariant product portfolio delivering resistance to humidity and water vapor, these products allow for the creation of aroma-sealed packaging and help to prevent cardboard boxes from slipping.
To meet even the most demanding specifications for oil and grease resistance of packaging materials, Clariant offers its range of fluorine-based Cartafluor® grease-resistant chemicals. As a result of intensive research and development, this product range is being constantly developed, not only to meet increasing barrier requirements but also to better respond to the growing demand for environmentally-friendly products and consumer protection.
In the size press, Cartacol® surface treatment chemicals improve printability and help reduce the penetration of ink into the paper for a significantly better print layout, paper gloss and print gloss.
Colorant applications often require fixing agents. The requirements as to their performance can vary significantly according to the quality of the process water, pH charge and the residual chemicals in the water circuit. To meet this need, Clariant offers a wide range of Cartafix® fixatives, which are not only used for fixing dyes but also for pigment retention and the elimination of impurities. Despite the financial crisis in the past two years, this segment has been a growth market.
