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 20 is a non-polar liquid and is immiscible with strong polar solvents such as water. In aliphatic and aromatic hydrocarbons, chlorohydrocarbons, ethers, esters, ketones and higher alcohols, WACKER® AK 20 is soluble in any proportion. In some anhydrous lower alcohols, in particular butanol, isopropyl alcohol and dioxane, the solubility is good. 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 infromation.

For pharmaceutical applications, we recommend specialty silicone fluids from our SILFAR® line.
Silicone fluids from our BELSIL® line are available for the cosmetic sector.
Whenever particularly high heat and shear resistance is required, we recommend silicone fluids from our AK stab, AK visc and AKC product lines.
Specialty grades of the product (available as WACKER® PLASTICIZER) will be needed for use as a silicone plasticizer in RTV-1 sealants.
