SIPERNAT D-10 is well known in the industry as excellent booster silica for liquid and powder defoamer formulations. s
During long term storage of liquid defoamer containing hydrophobic booster silica, how-ever, sedimentation may occur.
This is especially the case when carrier oils of low viscosity like mineral oil are used.
AEROSIL fumed silica is o en used to increase the viscosity and thixotropy of liquid formulations such as epoxy resins and special polyurethane systems.
Therefore, we systematically studied the eff ect of select-ed AEROSIL fumed silica grades on the sedimentation stability of diff erent defoamer formulations containing SIPERNAT D-10 as booster silica.
Within the test pro-gram, we varied the type of mineral oil and surfactant and evaluated the infl uence of small amounts of water.
The test program was set up and interpreted according to a systematic design of experiments (DOE).
From our experimental design, we were able to draw the following conclusions for the development of long term stable defoamer formulations:
•SIPERNAT D-10 alone is more stable against sedi-mentation in higher viscosity naphthenic oil than in lower viscosity white oil.
Dimethicone (and) Silica.

Chemical Properties
white powder
Definition
A colloidal or jellylike hydrated form of silicon(IV) oxide (SiO2), made by adding an acid (such as hydrochloric acid) to a soluble SILICATE.
• Higher SIPERNAT D-10 concentrations reduce the separation of the oil phase. Furthermore, the defoamer activity is signifi cantly enhanced.
• Addition of AEROSIL fumed silica generally elevates the sedimentation stability of SIPERNAT D-10 containing defoamer formulations.
Most common AEROSIL grades can be used although hydrophobic and / or high surface area grades are usually the more eff ective anti-settling agents.
• Hydrophilic AEROSIL grades provide an additional boosting eff ect and further enhance defoamer activity.
• The presence of surfactants and / or water can have a detrimental eff ect on the sedimentation stability of booster silica containing defoamer formulations
Preparation of Samples The following silica grades from Evonik Industries were used: SIPERNAT D-10,
Influence of SIPERNAT D-10 concentration The amount of SIPERNAT D-10 itself plays a major role in the sedimentation stability of a mineral oil defoamer formu-lation:
Increasing the concentration of SIPERNAT D-10 from 2 % to 6 % by weight reduces the phase separa-tion signifi cantly.
However, within the normal application range from 2 to 6 weight % of SIPERNAT D-10, the hydrophobic booster silica by itself is not able to form a stable three-dimensional network necessary to achieve long term sedimentation stability.
Especially low viscosity mineral oil formulations need gelling / anti-settling agents such as AEROSIL fumed silica.
