A PROCESS FOR PREPARING A COATING COMPOSITION FOR PAPER AND BOARD

摘要

A process for preparing a dry coating composition for paper and board includes mixing at least one pigment and at least one binder and pulverizing the obtained mixture, and wherein 25% to 100% of the pigment has particle size D90 from 10μm to 50μm before mixing with the binder. Also described is the use of pigments having a particle size D90 from 10μm to 50μm in the production of pulverized dry coating composition for paper and board for improving the surface strength of a coating, which is made by dry coating a paper or board with the dry coating composition.
