Application


SiSiB® VF6965 is used for defoaming agent, lubricating oil, and grease which can improve the corrosion resistance and solvent resistance. It is also used as an efficient defoaming agent and fabric finishing agent for spin printing and dyeing, which provides smaller surface tension, lower refractive index, and oil resistance and water resistance.


  • Base polymer or reactive modifier in fluorosilicone rubbers and gels


  • High-performance sealants, potting compounds, and adhesives


  • Fuel- and solvent-resistant gaskets and O-rings


  • Aerospace and automotive elastomer systems

Packing and Storage


SiSiB® VF6965 is supplied in 5Kg, 20Kg pails and 200Kg steel drums.


In the original unopened packaging, SiSiB® VF6965 has a shelf life of 24 months.
