  • antifoam agent
  • water-repellent agent
  • liquid dielectric for electrical and electronic equipment
  • heat-transfer oil
  • polish additive
  • plastics additive
  • additive for textile and fiber auxiliaries
  • minimal change in physical properties over a broad temperature range
  • excellent water-repellent properties
  • good dielectric properties
  • low surface tension and thus high surface activity
  • chemically highly unreactive
  • low solidifying point
  • high flash point
  • high heat resistance
  • good solubility in a wide range of solvents

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.


 

Due to AK 350 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. AK 350 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, AK 350 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.

Storage

The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
