Preparation of nondusting free-flowing pigment concentrates |
摘要 |
The invention relates to a process for preparing nondusting free-flowing pigment concentrates with removal of the water from pigment suspensions comprising polymers and dispersants in a fluidized bed drier. The resulting bead-form pigment concentrates are nondusting and readily free-flowing. The invention further embraces the use of pigment concentrates prepared in this way for coloring plastics and polymers.
