SILFOAM® SE 4260
SILFOAM® SE 4260 is a silicone antifoam emulsion which is especially designed for applications in cold climates.
It shows an extended frost stability and can be applied at temperatures below 0 °C.
SILFOAM® SE 4260 can be applied in a broad range of applications.
In particular it is used in the oil & gas industry for drilling fluids.
SILFOAM® SE 4260 is applicable as internal antifoam agent in the drilling fluid to control foam.
It is also applicable as defoamer for addition on-demand.
Preliminary compatibility and stability tests should be performed on the system to be defoamed.
The amount to add to liquid formulations depends on the desired degree of foam control, but usually is between 0.1 and 2%.
If feed pumps are used, they should be of the low shear-force type.
