SiSiB® HF2050 is available in different viscosities and different Si-H.
SiSiB® HF2050 is used as crosslinkers 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.
