APPLICATIONS
For gloss paper, premium coated
high gloss Art paper and high quality coated
board.
PROPERTIES
- Selected, High
Brightness, Natural Ground Calcium Carbonate
(Limestone)
- Micro
Crystalline Rhombohedral particle shape
- Supplied in
Predispersed slurry form
- Very fine,
optimized and controlled particle size
distribution.
Special
Advantages :
- High
brightness-low OBA demand
- Superior, high
gloss development-reduces the need for High
Glossing Clay Plastic Pigment.
- Requires lower
calender pressure for gloss development
resulting in improved optical properties
stiffness and bulk for coated paper and
board
- High solid
coating-improves the optical and physical
coverage of coated paper and board
- Improves the
runnability on low and high speed coaters
due to build-in water retention
- Improves the
water retention of coating colors-reduced
need for expensive water retention agents
- Improves the
water retention of coating colors-reduced
need for expensive water retention agents
- Lower binder
demand compared to high glossing clays
- Better
printability and improved ink gloss
development due to defined particle size
distribution
