WACKER® AK 100 is a linear, non-reactive polydimethylsiloxane with a viscosity of approximately 100 mm²/s. Its chemical structure gives it an exceptional property profile that distinguishes it from organic materials like mineral oils. It has a high flash point, demonstrating its resistance to ignition. It also exhibits high heat resistance and good solubility in a wide range of solvents.

Application Details
  • Due to WACKER® AK 100 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 100 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 100 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.
