HOW TO EMULSIFY IT
foam DMS-100 is not water soluble but it can be emulsified with (FAE-1830) as follow:
1. Charge 1 part foam DMS-100
2. Add 2 parts 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.
