Remark: SiSiB® HF2050 is available in different viscosities and different Si-H content.
SiSiB® HF2050-H55 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-H55 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.
