Due to the iron‐siloxane additive, HT‐110 High Temp Silicone Bath Fluid has a brownish-murky color and an odor when heated. If bath instrumentation needs to be visible within the bath, we recommend the DPDM‐400 or PM‐125 High Temp Fluids which are clear, colorless and odorless.
In the presence of oxygen or air (open system), the HT‐100 High Temp Silicone Bath Fluid has a greater resistance to high temperatures (see Table 1) than conventional PDMS Silicone fluids that are not heat‐stabilized.

Technical Details & Test Data
- Effects of Temperature
- HT‐110 High Temp Silicone Bath Fluid does not boil or flash at temperatures as high as 288°C, and withstands long heat exposure without gumming or oxidizing. The maximum service temperature of HT‐110 Bath Fluid will vary with each specific application.
- HT‐110 High Temp Silicone Bath Fluid remains pourable to ‐40°C. In addition, the fluid shows very little change in viscosity and flow characteristics over a wide temperature span.
- Effects of Shear
HT‐110 High Temp Silicone Bath Fluid provides stability and uniform performance in mechano‐fluid devices and controls. Because uniform flow characteristics under shear are rigidly controlled, uniform performance from lot to lot is assured. Even after repeated or long service at high shear rates, this fluid has little or no permanent change in viscosity, and the damping effects remain nearly constant.
At low shear rates, Clearco Silicone Bath Fluid behaves like a Newtonian fluid, showing little appreciable drop in apparent viscosity with increasing shear.
At extreme shear rates above 2000/s, Silicone Bath Fluid shows a slight deviation from Newtonian behavior.
Any change in the apparent viscosity of HT‐110 High Temp Silicone Bath Fluid die to shear is only temporary. When the shear stress is removed, the viscosity returns to its original value.
- Solubility
HT‐110 Silicone Bath Fluid is soluble in most aliphatic hydrocarbon solvents and chlorinated solvents, including gasoline, heptane, VM&P naptha, xylene, toluene, methylene chloride, perchloroethylene, ethyl ether and hexyl ether.
It is partially soluble in such solvents as 99% isopropyl alcohol, heptadecanol, acetone and insoluble in such liquids as water, ethyl alcohol, 70% isopropyl alcohol, ethylene glycol, propylene glycol and diethylene glycol stearate.
- Limitations
This product is neither tested nor represented as suitable for medical or pharmaceutical uses.
