Huber Paper Silicates Solutions

Functional Pigments = Exceptional Results

Applications:

Board Grades
Huber's Hydrex® sodium magnesium aluminosilicate and Zeolex® sodium aluminosilicate grades provide folding boxboard, white top, high brightness and opacity and reduce unattractive mottling. In addition to improving product aesthetics, they improve economics by reducing the need for expensive chemical pulp and can additionally cut costs by replacing titanium dioxide if needed.

Carbonless Copy Paper
For carbon-free copying, a paper must have fast color development, a high brightness and deliver uniform quality. This is exactly what Huber's Zeocopy® sodium aluminosilicate offers reliable copying paper, without carbon, every time.

Mechanical Printing Papers
For newspaper, improved news-print, and  directory paper Huber's Hydrex and Zeolex silica grades provide excellent brightness and opacity, improved color printability, less print-through in coldset-offset and flexo printing, and a higher friction during the winding process.

Fine Paper
Delicate papers such as envelope paper or thin printing paper are particularly at risk for print through. Hydrex and Zeolex silicates reduce print-through in flexo printing while simultaneously offering high opacity.

Specialty Papers
In decor and filter tipping paper, Hydrex and Zeolex silicates offer titanium dioxide extension, superior brightness, and improved print quality. 
 
Peroxide Bleaching
During the mechanical bleaching process, stabilizers are needed. Huber's Zeopol® liquid sodium silicate stabilizes hydrogen peroxide and additionally serves as a pH buffer and an aid in the complexation of metals.

Cores
Zeocore® is a modified liquid sodium-silicate based core adhesive which is ideal for high strength and heavy duty cores. It offers excellent core strength for a competitive price.

Retention Aids
For fine paper and board Huber's Zeofloc® silica grade offers excellent dewatering performance, improved filler and fiber retention, and good formation. Zeofloc is a temperature activated polysilicic acid.
