- Boost paper optics with improved opacity and brightness
- Improve surface properties and reduce ink demand
- Provide faster dewatering
- Reduce drying time
- Impart good mechanical properties to the paper
- Improve paper smoothness
- Improve coating hold out
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
