WACKER® AK 20000

1 of 217 products in this brand
WACKER® AK 20000 is a linear, non-reactive polydimethylsiloxane with a viscosity of approximately 20000 mm²/s. Its chemical structure gives it an exceptional property profile that distinguishes it from organic materials like mineral oils. It exhibits excellent water-repellent properties, good dielectric properties, and low surface tension, resulting in high surface activity.

Applications & Uses

Home Care Applications
Application Details
  • Release agent
  • Hydraulic fluid
  • Antifoam agent
  • Water-repellent agent
  • Liquid dielectric for electrical and electronic equipment
  • Polish additive
  • Plastics additive
  • Additive for textile and fiber auxiliaries
  • Damping medium
  • Due to WACKER® AK 20000 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 20000 is a non-polar liquid and is immiscible with polar solvents such as water or short-chain alcohols.
  • In aliphatic and aromatic hydrocarbons, chloro-hydrocarbons, ethers, esters, ketones and higher alcohols, WACKER® AK 20000 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.
  • Whenever particularly high heat and shear resistance is required, we recommend silicone fluids from our AK stab, AK visc and AKC product lines.
