Fimcarb Wet Ground Calcium Carbonate (WGCC) Slurry grades are used as Coating pigments in Pre Coat and or Top coat of Boards, in Mat, Dull, LWC & ULWC coated papers, as it provides-
- Higher brightness
- Good print quality and print gloss
- Lower dispersant demand
- Lower binder demand
- Lower production cost
- Lower viscosity of coating color at high shear
- Easy dispersibility
- higher solids content of coating slip
- Consistency and better quality control during paper coating
- No make down cost from dry to wet, as it is supplied in ready to use slurry form
- Provides dust free and safe working environment, due to its slurry form
Recommended Grades
- Fimcarb– with particle size of d60 to d98 < 2micron
TALKRON Talc in Paper Applications
Wolkem’s Talc Milled Grades are used as a filler and coating pigment in rotogravure & offset printing process, in colored papers, labels catalogues, LWC and HWC paper/ Board
Wolkem’s Talc as a filler provides
- Decreased porosity
- Improved opacity
- Reduces cost
- The print benefits also allow the increased usage of calcium carbonate in coating formulations in paper mills operating under alkaline conditions.
- Accelerates water drainage in the paper machine wet-end and impart good cross-sectional strength to paper.
- Talc’s softness imparts good folding properties to paper board, making the sheet less abrasive on cutters and other converting equipment.
Wolkem’s Talc as a coating pigment provides
- Improved gloss
- provides smoothness to surface
- Imparts print opacity
- reduces wear and tear of machineries
- Reduces use of expensive OBA.
- Provides a silky feel for matt paper, thereby enhancing reader comfort and touch
Further talc
- Provides elimination of core burst problem of LWC-Rotogravure printing.
- Better printability for gravure printed papers.
- Silk feel for wood-free matt / Semi matt papers.
- Water based barrier coating for grease resistance
- Recycle ability
- Low friction properties
- Decreased premature breakage of the ink capsules in NCR (no carbon required paper)
