Chemical composition
Combination of higher hydrocarbons and fatty derivatives
Fields of application
GREIMIN SST is particularly suitable for defoaming of aqueous surfactant-containing media.
- Defoaming of surfactant-containing waste waters
- Defoaming in paper processing (size press, sizing compound)
- Defoaming of coating colours
Storage behaviour
The product can form a turbidity or sediment at longer storage. This however does influence neither the effectiveness nor the dosing-ability. The viscosity of the product is temperature-dependent.
GREIMIN SST is not frost-sensitive. The product can be brought into the original state at any time by stirring, pumping or slight warming.
GREIMIN SST is storable in closed delivered packagings under normal temperature conditions (from +5°C to +30°C) at least a year.
Application
GREIMIN SST is used undiluted, but may also be used in diluted form as an emulsion. The product respectively the emulsion has to be stirred or shaken, shortly before the application.
Usually the product is used in a concentration of 0.01 to 0.05 %. Suitability and dosage are to be determined through own practice tests on site in each case.
In order to reach a good distribution and small proportioning-amounts, it is recommended to add GREIMIN SST at a place where the liquid is turbulent.
Please do not add the assessed amount of the defoamer at the same time. Fundamentally wait a certain time after addition of a small quantity until a good distribution with the watery liquid occurred. Judge the achieved effect only then and add a further amount if necessary.
