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.
