| An attempt was made to disperse sulfonated polyester pellets in hot water, but the material clumped up. How can I correct this problem in the future? |
| |
| To avoid clumping, best results are obtained when the pellets are gradually added rather than making a rapid, single addition of all the material to the mixing tank. A high-speed mixer helps keep the pellets agitated while dispersing in water and should keep them from settling to the bottom of the tank. If settling does occur, continue mixing until the material dissolves. Heating the water will lower the time needed for dispersing. |
