WACKER® AK 200 is a linear, non-reactive polydimethylsiloxane with a viscosity of approximately 200 mm²/s. Its chemical structure gives it an exceptional property profile that distinguishes it from organic materials like mineral oils. It exhibits low surface tension, resulting in high surface activity. Additionally, it is chemically highly unreactive and has a low solidifying point.

Applications

For typical application fields of VINNAPAS® 5005 N, refer to the section "application". We recommend VINNAPAS® 5005 N in tile adhesives in a dosage of up to 2%.

Processing

For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS® 5005 N with the other dry ingredients in appropriate equipment. Temperatures should not be allowed to rise excessively during mixing because otherwise the dispersible polymer powder could agglomerate by virtue of its thermoplastic properties. The mortar is prepared for use by adding the recommended amount of water and mixing mechanically or by hand. Since hand mixing generates little shear force, we recommend allowing the fresh mortar to slake for 5 minutes and then stirring it again. This is usually unnecessary where mechanical mixers are employed.

Application Details
  • Due to WACKER® AK 200 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 200 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 200 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.
