Chemical Resistance
FluoroResist exhibits outstanding chemical resistance and excellent barrier properties. It is virtually unaffected by most corrosive chemicals commonly encountered in industry.
Among those substances that FluoroResist is resistant to are strong mineral and oxidizing acids, alkalis, metal etchants, liquid oxygen and essentially amines (e.g. aniline, dimethylamine).
Typical of fluoropolymers, FluoroResist is attacked by metallic sodium and potassium. Rate of attack is function of exposure time and temperature.
FluoroResist and other fluoropolymers can become slightly plasticized by contact with certain halogenated solvents, but this effect does not normally impair its usefulness. After contact ceases and the part is allowed to dry, the mechanical properties return to their original value, indicating that no chemical attack has occurred.
FluoroResist is compatible with liquid oxygen (LOX) as measured by the National Aeronautics and Space Administration test MSFC-SPEC-106B. It is resistant to nitrogen tetroxide (NTO) and monomethylhydrazine (MMH).
