HOW TO EMULSIFY IT

 

Rockdefoam DMS-100 is not water soluble but it can be emulsified with (Rockapon FAE-1830) as follow:

1. Charge 1 part Rockdefoam DMS-100

2. Add 2 parts Rockapon FAE-1830

3. Mix it for a while to uniform

4. Add certain quality of DM water to obtain desired percentage of defoamer emulsion after 2-3 hours

5. Add 0.1% preservative.

 

Please note:

  • Water must be di mineralize water
  • No need to any heating but if you want to heat ,the temperature must not be more than 45°C-50°C
  • Stirrer RPM of must not be more than 45-55, the viscosity and power of defoamer emulsion will be effected accordingly.
  • If you do not add water into base defoamer and emulsifiers, it will separate after sometimes ,hence you can not present 100% solid.

 

Note

 

 

 

According to our best knowledge and technical experiments, the above data is true and accurate. Regarding to variety of consumption procedures, it is recommended to evaluate the information before use.
