Usage of Fluorosilane coupling agent

  1. Surface treatment method of epiFluorosilane coupling agent

  In this method, the two interfaces of inorganic matter and polymer are connected together by Fluorosilane coupling agent to obtain the best wetting value and dispersibility. In the surface treatment method, the silane coupling agent needs to be acidified into a dilute solution to facilitate full contact with the treated surface.

  2. Treatment method using Fluorosilane coupling agent in alcohol aqueous solution

  The process of this method is simple. First, an alcohol aqueous solution is prepared from 95% EtOH and 5% H2O, and AcOH is added to make the pH 4.5-5.5. Add silicon coupling agent under stirring to make the concentration reach 2%, and after hydrolysis for 5min, the hydrolyzate containing SiOH is formed.​​

  3. Treatment with aqueous solution of Fluorosilane coupling agent

  This method is mostly used in industrial processing of glass fibers. The specific process is to first dissolve the alkoxysilane coupling agent in water, and make it into a 0.5%-2.0% solution.

  4. Solution treatment with organic solvent of Fluorosilane coupling agent

  When using the Fluorosilane coupling agent solution to treat the substrate, the spray method is generally used. Before treatment, it is necessary to master the amount of silane and the water content of the filler.

  5. Overall blending method

  The overall blending method is to mix the Fluorosilane coupling agent stock solution into the resin or polymer before the filler is added. Therefore, it is required that the resin or polymer should not react with the silane coupling agent prematurely, so as not to reduce its tackifying effect.
