The maximum allowable operating temperature is 5728 F( 3008 C). These
resins are available for operation at cryogenic temperatures.
As econd high-temperature formulation with aluminumcan be operated
up to 12008 F(6498 C). This high-temperature type requires baking for agood
cure. It is also water repellent.
The silicone resins can be used in contactw ith dilute acidsa nd alkalies,
alcohols, animal and vegetable oils, and lubrication oils.T heya re also
resistant to aliphatic hydrocarbons, but aromatic solventss uch as benzene,
toluene, gasoline, and chlorinated solvents willc ause excessive swelling.
Table 4.28 lists the corrosion resistance of methyl appended silicone with
selected corrodents. Reference [1] provides additional listings.
