Cost Savings, Made Simple. With Imerys fillers and coatings, the more you print, the more you save.

In addition to the offset printing of books, brochures, and magazines, multipurpose papers for writing, copying, and digital printing are some of many products you produce everyday. This usually means the use of uncoated, wood-free paper increases, which explains why it is now the largest segment within the writing and printing industry today.

Apart from the cost savings associated with fiber replacement, utilizing filler can:

x Improve optical performancex Control friction (through absorption of pitch and stickies)x Better printability (by controlling porosity, smoothness and ink penetration)x Improve drainage, decreased drying energy

PRINT AWAY! IMERYS fillers and coatings provide more ways to save on paper production costs.

I-60* low bright filler is mainly for newsprint machines (with typically up to 12% loading levels)

To minimize coating related

issues, all coating grade GCC

is produced in slurry form and is

optimally dispersed to avoid

any settling or agglomeration.

Due to its uniform PSD,

improved gloss and smoothness of

the coated paper or board is a key feature of

our coating grade GCC.

Benefits of Using WGCC Filler in place of powder GCC or Talc:

x Low abrasion compared to locally available talc and powder GCC due to its controlled wet grinding and uniform particle size distribution.x Better control over the wet end process and machine maintenance and runnability due to the high purity levels from imported raw materials.x Better optical properties with high brightness and controlled PSD

Carbital-60 and Carbital-70 are primarily used for pre-coat formulation. These coarser grades are used to cover base board or paper roughness and provide a bet-ter surface for top coating.

Carbital-90, Carbital-95 and Carbital-97 are fine grade GCC used for top coat applications in conjunction with clay (as required).

Carbilux is a very fine grade GCC for top coat applications. It helps maintain gloss and smoothness of the coated paper or board, even at low clay levels. It also aids in improving water retention of the coating color.
