Dissolve Method
1. Put all the solvents into the reactor
2. Put the ES-830 solid into the reactor while stirring
3. After adding all the ingredients, raise the temperature of the reactor to 90-100 degrees and stir for 2 hours. When using MEK and acetone, the maximum pressure of the reactor: 2kg/cm2
4. Turn off the heating system and continue stirring for one and a half hours to allow the reactor temperature to drop naturally.
5. Stop stirring, the solution needs to be filtered, and put the solution into a 200kg bucket
Commonly used Solvent
MEK, toluene, acetone, butanediol, DBE, Solvesso, cyclohexanone, celusoleacetate, isophorone, etc.
