Processing

  • Due to WACKER® AK 500000 many diverse applications, no general processing information can be provided.
  • Parameters will vary from application to application.
  • Available in a range of viscosities, WACKER® SILICONE FLUIDS AK are miscible with each other in any ratio.
  • The standard product's viscosity can thus be altered to suit your individual needs.
  • WACKER® AK 500000 is a non-polar liquid and is immiscible with polar solvents such as water or shortchain alcohols.
  • In aliphatic and aromatic hydrocarbons, chlorohydrocarbons, ethers, esters, ketones and higher alcohols, WACKER® AK 500000 is soluble in any proportion.
