AEROSIL®, AEROXIDE® and AERODISP® for sizing and coating of paper, films and textiles
Today, numerous types of substrates such as papers, films, textiles, etc. are available to the print industry.
Print media are purposely designed to function with a specific printing technology and ink or toner. Printable products are classified by the markets in a wide variety of ways. In general, these grades can be categorized by:
Basis weight & furnish
Aesthetics (color, gloss, texture)
Surface treatment and finish
End use or market segment
Evonik Industries offers a wide range of products specifically engineered, using precise controls in the manufacturing process, to meet the following effects:
Adjusted matt or soft touch effect
Defined gloss level
Prevention of glue penetration
Many components used in the paper and film industries are applied onto the substrate surface, (e.g. as a coating), or dispersed in the paper or film as a filler.
SEM cross-section of paper with inorganic filler and coating
Other components used in the paper industry are formulated for surface treatment (e.g. sizing) in order to fulfill special quality requirements or to prepare the surface for an after-treatment, such as a coating.
|Industry Brochure: AEROSIL® for Photo Inkjet Media (pdf, 2,58 MB)
The Industry Brochure "AEROSIL® for Photo Inkjet Media" gives an overview about the use of AEROSIL® fumed silica and AEROXIDE® fumed alumina in microporous photo inkjet media.
|Industry Information 2243: Products for the paper and film industry (pdf, 762,71 KB)
Inorganic materials for print media In addition to describing the production of pyrogenic metal oxides, precipitated silica and silicates, the brochure devotes a section to the effects that can be obtained by the use of our products in paper applications. At the core of this brochure is a detailed section on the large variety of paper types and the advantages gained by using our products, because there are now many different types of substrate (paper, film, fabric, etc.) for printing. The best printing results are achieved with the ideal combination of printing technology and the appropriate ink or toner.
|Technical Information 1322: Paper Sizing with AERODISP® Fumed Silica Dispersions (pdf, 1,10 MB)
The Technical Information No. 1322 describes the new concept of Evonik of improving the inkjet print performance of uncoated office and printing paper by applying a thin fumed silica coating directly on the paper machine (size press).
|Technical Information 1331: AEROSIL® Fumed Silica and AEROXIDE® Fumed Alumina for Glossy Photo Inkjet Media (pdf, 1,37 MB)
The Technical Information No. 1331 describes the entire development and production process for photo inkjet media with fumed metal oxides.
|Technical Information 1357: AERODISP® Fumed Silica Dispersions as an Anti-Slip Agent for Paper Bags (pdf, 429,15 KB)
Paper bags require a sufficient degree of surface friction to enable stable stacking during transport of the bags. This technical information describes the use of AERODISP® fumed silica dispersions as a very effictive replacement for simple colloidal silica. Very high coefficients of static friction can be reached with very little amounts of fumed silica.
