PROCESS FOR PREPARING PIGMENTS DISPERSIBLE IN PAINTS AND PLASTICS CONCENTRATES |
摘要 |
A process for preparing an improved pigment which is readily dispersible in paints and plastics concentrates is provided. In accordance with the process, a particulate pigment is mixed with water to form a slurry thereof, and a surface active agent is mixed with the slurry so that the pigment therein is coated therewith. A preferred surface active agent is a mixture of ethoxylated sorbitan derivatives, non-ethoxylated mono and diglycerides and ethoxylated mono and diglycerides. After the pigment has been coated with the surface active agent, the coated pigment is dried. |
