Application Details
  • Due to WACKER® AK 12500 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 12500 is a non-polar liquid and is immiscible with polar solvents such as water or short-chain alcohols.
  • In aliphatic and aromatic hydrocarbons, chlorohydrocarbons, ethers, esters, ketones and higher alcohols, WACKER® AK 12500 is soluble in any proportion.
  • Before the product is used with solvents for the first time, it is advisable to perform a lab-scale test.
  • When solvents are used, please remember to read the appropriate hazard information.
