Application


  • SiSiB® HF2050-H75 is primarily used as cross linked silicones for curing vinyl-functional silicone fluids. With different Si-H content, it can provide good flexibility in formulating RTV-2 silicone rubber. Curing is affected by a platinum catalyst resulting in an addition reaction between the hydrogen and the vinyl group of the silicones.


  • SiSiB® HF2050-H75 hydrogen silicone oil can also be used as a reactive intermediate to make organo-modified silicones via hydrosilations. Functional groups normally attached in this way include allyl terminated polyethylene or polypropylene glycols, amines, and epoxies.


Packing and Storage


  • SiSiB® HF2050-H75 is supplied in 5Kg, 25Kg pail or 200Kg steel drum.


  • In the original unopened packaging, SiSiB® HF2050-15H75 has a shelf life of one year in a dry and cool place.
