Degussa begins production of alumnia at US plant

Degussa’s AEROSIL business line has commenced production of fumed alumina and cationic-silica dispersions at its North American dispersion plant in Mobile, Alabama.

These specialty products are ideally suited to meet the demanding needs of the highly competitive inkjet paper industry. Production of fumed alumina and cationic silica dispersions within North America will expand Degussa’s portfolio of domestically produced specialty dispersions. They are used to produce inkjet paper coatings for commercial as well as non-commercial applications, ranging from birthday cards and CD labels to high-end glossy photo paper.

The inkjet paper industry recognizes the value of microporous paper coating systems for use with dye and pigment-based ink systems alike. Degussa is committing its resources toward strengthening and enhancing the quality of products available to this industry.

‘Degussa’s alumina and cationic silica dispersions enable inkjet paper manufacturers to produce inkjet printable products that offer high gloss, instant dry times, optimum resolution, excellent colorant fixation and outstanding rub-, smear- and water-resistance. The high solids content of these products enables paper manufacturers to realize cost savings - from development to production,’ said Leo Nelli, technical specialist for Degussa AEROSIL products.

‘Inkjet paper is the fastest growing sector in the paper market,’ said Dr Steffen Hasenzahl, marketing manager for Degussa AEROSIL products. ‘Our new dispersion plant gives us the opportunity to provide paper producers with more choices and better products.’

Degussa has operated its dispersion plant in Mobile since May 2005. This has more than doubled Degussa’s global production capacity for its portfolio of AERODISP products.

AERODISP products also add value by reinforcing latex systems; increasing clarity and scratch resistance of paint and coatings; treating metal surfaces; and imparting anti-slip properties to paper and textiles; as well as stabilizing and enhancing personal care and household products. The milky white liquid is uncomplicated to handle and store.
