Chemical resistance

  • It is resistant to dilute acids and alkalis and to most aqueous solutions.
  • It is very resistant to a wide range of organic and inorganic chemicals. As each application may vary in chemical composition, pressure, flow rate, relubrication needs, and equipment design, it is recommended that silicone compound be tested before adopting regular use.
