Mastering paper coating techniques
To improve the coating of paper and cardboard, Coatex, a subsidiary of the Arkema Group, today applies the latest breakthroughs in the synthesis of hydrosoluble polymers. Its product range is based on its unique expertise in mastering techniques related to the viscosity (rheology) of coating colors applied to the surface of paper. Its range of products includes rheology modifiers (RheocoatTM, RheocarbTM) and polyacrylate dispersants (TopsperseTM).
Coatex has developed two new environmentally sound solutions aptly suited to inkjet paper which help improve the surface quality of the paper, and reduce manufacturing costs and cycles, and therefore also wastewater emissions.
Rheocarb™ J 40 rheology modifier improves water retention and the dispersion of coating color particles. Topsperse™ JX A dispersing agent protects pigments from flocculation, and controls the stability of coating color viscosity.
For whiter paper
As the world’s third largest producer of hydrogen peroxide (or oxygenated water) and the European leader in sodium chlorate, today the Arkema Group is a major supplier of pulp and paper bleaching products under the Alpure® and Albone® brands. It has production facilities in Asia, Europe and North America.
Stable, colorless and biodegradable, hydrogen peroxide does not produce any by-products.
Arkema's liptol de-inking agents are made from fatty alcohols specially developed for paper de-inking. They help achieve high brightness while minimizing fiber loss. The liptol range also has a beneficial effect on the following parameters:
- cleanliness of the paste
- performance of de-inking cell
- stickies (impurities)
- formation of deposits
- operation of the paper machine
