Fumed Silica – Hydrophilic and Hydrophobic
For over 70 years Evonik’s AEROSIL has been a market leading brand of fumed silica. With a unique range of both hydrophilic and hydrophobic grades available the number of applications are endless. Fumed (pyrogenci) silica is composed of synthetic silicon dioxide (SiO2) which is entirely amorphous, eliminating the risks posed by crystalline silica.
One of the main applications for fumed silica is increasing the viscosity, pseudoplasticity and thixotropy of a wide range of liquid systems. However there are many more applications besides this common use case. Evonik’s™ AEROSIL range is the most extensive range of fumed silica on the market, with many of their products tailored for particular applications. The versatility of AEROSIL means that it can be found all around us, from the paints on our walls to the fertilizers on our crops.

The importance of rheology in epoxy resins
As a formulator of epoxy resins, you know that rheology control is an important consideration when designing a system. Take proper care over the rheology profile and you will have a product that resists sedimentation, has excellent shelf life stability, is easier and more accurate to blend (2k systems), can be applied with ease and has a high level of anti-sagging performance. Some of these factors are important before, during and after application – making yours and your customers’ lives easier.
AEROSIL fumed silica has been a successful rheological additive in epoxy systems for decades. There is a good chance you will have worked with it at some point. Its success stems from the versatility it gives formulators in building viscosity, thixotropy and in controlling rheology over a wide range of shear and temperature conditions.
There are many factors that influence the successful use of AEROSIL fumed silica in epoxy resins. Let’s take a look at how fumed silica works, how to choose the right grade for your system, how to use it properly and what to bear in mind about the interactions other components can have on its efficacy.
How does fumed silica thicken liquid systems?
First of all, let’s take a look at how AEROSIL fumed silica works as a thickening agent. Fumed silica is supplied in the form of agglomerates that need to be broken down under high shear into aggregates. The latter would ideally have a particle size in the region of 100-300 nm. To achieve this breakdown of particle size you would incorporate the fumed silica with a dissolver, planetary mixer, triple roll mill or kneader. Propeller stirrers are NOT suitable for this process! Dissolvers and planetary mixers are the most popular due to the ease of continuous incorporation and lower energy demands.
Once the particles have been broken down they will reform as a continuous 3D gel network, imparting a yield value and higher viscosity at rest. This is a reversible process – in that applying shear will break the network down and decrease the viscosity. Once again, the network can reform. This behaviour is what gives rise to the shear thinning and thixotropic behaviour AEROSIL is so well known for in epoxy resins.
OK, so that’s how it works on a mechanistic level. To understand why some grades work in certain systems, but not in others, we need to look at the interactions between the fumed silica particles. AEROSIL grades come both untreated (silanol surface groups) and with hydrophobic silane treatments (various options, some silanol groups remain). Interactions between the silanol groups are responsible for the formation of stable networks. In non-polar fluids, this interaction is maximised. When trying to thicken a polar fluid these molecules solvate the AEROSIL and lead to a destabilisation of the gel network. This is why relatively large amounts of hydrophilic silica are required when thickening water or ethanol*.
How to thicken an epoxy resin with fumed silica
It is interesting to note that the presence of a small concentration of polar molecules in a non-polar fluid can have a synergistic effect in the thickening behaviour; through a bridging mechanism. Consider the use of a polyamine curing agent for example. This effect works the other way above a certain critical concentration due to the solvating effect mentioned above.
Hydrophilic fumed silica is often not suitable for use in epoxy resins as many grades are polar in nature, solvating the AEROSIL. Epoxies also have curing agents added to them which can destabilise the gel network.
Notice how the hydrophobic grades increase viscosity in this polar resin to the greatest extent. Addition of polar hardener molecules then massively boosts the viscosity of the AEROSIL 300 due to the bridging effect mentioned earlier. This effect is short lived however, as the fumed silica particles are increasingly solvated by polymer molecules containing hydroxyl groups that originate during the curing reaction. In conclusion, if you want a stable viscosity profile through cure, then you need to use a hydrophobic AEROSIL grade such as AEROSIL R 202, AEROSIL R 208 or AEROSIL R 805. These grades have hydrophobic groups on the surface to shield the remaining silanol groups from undesired wetting. Note that both silanol groups and the hydrophobic chains contribute to thickening with these grades.
AEROSIL fumed silica as an anti-settling agent
Fillers are frequently employed in the formulation of epoxy systems, either to improve performance like shrinkage or to reduce cost. These particles are prone to settlement if not properly stabilised. AEROSIL fumed silica can slow down, or even prevent, the settling of fillers and pigments. After extended storage times, some sediment may be seen but it is often soft and easy to resuspend. This effect is attributable to the increased yield value that fumed silica imparts. Either AEROSIL R805, R202 or R208 would perform best in this function.
Fumed silica for the thickening and thixotropy of hardeners for epoxy resins
By adding fumed silica to the less viscous hardener component, blending mistakes can be avoided and a more homogenous mixture obtained. Note that fillers can be suspended in the hardener component with the proper choice and use of AEROSIL fumed silica.
Now here is where the recommendation can change from those made so far, depending on the polarity of your hardener (see Figure 4). Non-polar polyaminoamides like VERSAMID 140 are thickened best by hydrophilic fumed silica grades (AEROSIL 300). In high polarity mercaptan hardeners, like CAPCURE 3-800, hydrophobic grades are the best (R805, R202 and R208). It is worth noting that the hydrophobic grades often have better storage stability though.
High performance fumed silica fillers in silicone rubber systems
Synthetic fumed silica grades have been used as reinforcing powders in silicone systems since the 1940’s. Fumed silica, in particular, has contributed to the success of silicone rubber. Initially, hydrophilic grades were the only option but then hydrophobized grades became available for more demanding applications.
This article gives an overview of the latest generation fumed silica for silicone rubber – AEROSIL R 8200. This hydrophobic silica is modified and treated via a series of physical process steps, which result in its characteristically low thickening effect and high level of reinforcement – when compounded into silicone rubber.
Particular focus will be paid to its use in two-component room temperature curing silicone rubber (RTV-2C), RTV-1 silicone sealants and in liquid silicone rubber (LSR) formulations.
Synthetic silica powders in silicone rubber
In addition to enhancing the mechanical strength of cured silicone products, silicas often give undesirable thickening properties as well. These can result in the “crepe hardening” effect in Heat Cured Rubber (HCR). Silicone compounds that have not been cross-linked become unworkable within just a few days of storage, making it difficult or impossible to process them further. For RTV systems it is crucial to get the correct balance of thickening and reinforcing effects.
It is possible to mitigate the effect of crepe hardening by hydrophobizing silanol groups on the fumed silica in-situ, during the compounding stage. However, the condensation by-product of water must be adequately removed from the compound, since it would seriously impair the properties of the cured compound. This is a laborious, time consuming and energy-intensive approach that also generates the need to treat the exhaust air generated.
EVONIK have been offering solutions to the above problem for many years – hydrophobically modified fumed silica. AEROSIL R 972 is a dimethyl- dichlorosilane treated fumed silica, which was introduced in 1962. Since then various new developments have been released for silicone rubber including AEROSIL R104, R106 and R 812S – all of which posses strongly hydrophobic surface treatments resulting from the modification with trimethylsilyl groups. These grades are highly effective options for the production of peroxide, condensation and additive cross-linked silicone compounds. For more difficult applications, there is AEROSIL R 8200
What are silica carriers? In what systems can I use them?
A versatile range of precipitated (SIPERNAT) and fumed (AEROSIL) silicas are available from EVONIK for absorbing liquids, such that they are converted into dry free-flowing powders. Why are these products highly efficient carriers for liquids? It is due to their high internal and interstitial pore volume. Many other materials commonly used as carriers only have external surface area available, for example, maltodextrin and starches
Grades can be chosen with different particle sizes, depending on the requirements of the end application. SIPERNAT 22 and 2200 are very coarse grades, which are more free-flowing and less dusty than some other products. They may be too large for certain applications, however. In this case, the formulator might choose SIPERNAT 22S, SIPERNAT 50S or AEROSIL 200. Conversely, these grades may be too fragile or dusty for particular applications.
How to dose liquid onto the silica carriers
Generally, the carrier should be put into the mixer first. Liquids should be dosed in as continuously and finely distributed as possible. In some special cases, where the absorbate has been liquefied through increased temperature, improved results can be obtained wherein the silica is added to the liquid.
It is important that gentle mixing is applied. Optimum results cannot usually be obtained with high pressure or high shear forces as they partly destroy the porous structure, desorbing any absorbed liquid.
To optimise flow behaviour and pressure stability of the absorbates, the liquid should be introduced as finely divided as possible. The best method is to atomise the liquid through a sprayer. If this is not possible then dripping is better than pouring. Ploughshare and paddle mixers are well suited to perform these kinds of mixing tasks. They have short mixing times and very low shear, so the particles remain intact. Avoid high-intensity mixing elements inside low shear equipment.
For fine particle carrier silica, the absorption capacity may vary a lot depending on the shear energy which is applied when the absorbate is made. Overshearing these products can lead to a reduction in the absorption capacity; due to damage done to the particle structure and uncontrolled agglomeration
ome noteworthy observations when making absorbates:
A low energy mixing device that fluidizes the dry carrier powder with minimum shear often works best but this depends on the physical properties of the liquid. Suitable mixers include ribbon, ploughshare or V-type “liquid-solid” blenders. Conical or Nauta-type mixers are also suitable.
In some cases, high shear can be used with caution – if the liquid has a high melting point and will solidify into agglomerates, with silica particles surrounding the droplets.
Generally, larger particle size grades have better flow properties. For some applications, such as in instant beverages, small particles are desirable; as they allow the powder ingredients to dissolve in the mixture without affecting flavour or texture.
Consider protecting the liquid from oxidation. High surface area materials can accelerate oxidation in unsaturated ingredients. In this case, choose a lower surface area SIPERNAT or AEROSIL product – or add an anti-oxidant to inhibit oxidation.
Optimize flowability and dustiness with the right loading level
As loading level increases, flowability reaches an optimum. This will depend on the properties of the carrier silica and the liquid being carried. When saturated, the carrier flow will become worse and dustiness is reduced
When mixing both SIPERNAT and other substances, dual-carrier applications are possible. These types of carriers can optimise cost, absorption capacity, dustiness and various other desired properties. For example, a dual-carrier made of maltodextrin and SIPERNAT 500 LS can optimize absorption capacity, costs, solubility and flavour profiles. The specific combination of dual carriers is dependent on several factors and needs to be based on the desired finished product. These factors include:
Absorption capacity of each carrier material.
Density of each carrier material.
Density of the liquid to be plated.
Volatility of the liquid.
Amount of insoluble material that can be tolerated in the system.
Flavour Applications
Flavour control is critical in the beverage and food industries since evaporative losses will impact the final product. This may occur either during manufacture or storage.
Kinetic considerations are significant when choosing a substrate to carry liquid flavours. Encapsulation techniques can be used to control these losses.
A study was conducted to investigate the effect of carrier type on the evaporation rate of a volatile flavour compound. Five SIPERNAT grades and one AEROSIL grade were compared to a competitive silica and silica gel.
Summary and what to do now
SIPERNAT and AEROSIL silicas have a high pore capacity, which enables them to efficiently convert liquids into free-flowing powders.

ASAP Application: Unstable Drug Candidate in Early Development
Anjali Agrawal, … Zeena Williams, in Accelerated Predictive Stability, 2018
3.2.1.1 Effect of coating agent
It was found that Aerosil R972 was much more effective in coating the API as compared to Aerosil 200.
ASAP results (not shown) of tablets with API coated with Aerosil 200 and Aerosil R972, respectively, also indicated that the Aerosil R972 coating resulted in more stable tablets.
Aerosil R972’s stabilizing effect compared to Aerosil 200 was assumed to be associated with its hydrophobic surface property, which might have resulted in reduced moisture uptake.
Thus, Aerosil R972 was selected to be the coating agent for manufacturing prototype tablet formulations.
