Usage
1. Use directly-Mix under dry base:
Mix Hydroxypropylmethy cellulose with other materials you need to add directly in the mixer.
When HPMC and other materials blend well,pour water to disperse and dissolve.
2. Mother solution first
First, pour 1/3 or 2/3 of the total water you need to add into the container.
Second, heat the water .when the water temperature is about 85 centigrade,add Hydroxypropylmethy cellulose continually at the same time keep stirring.
Third ,When the solution becomes a kind of slurry ,please add the rest of water while keep stirring until the solution turns transparent
