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.
* 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.
