Evonik Crosslinker 120, part of the Crosslinker 100 series, consists of polydimethylsiloxanes containing SiH groups within the polymer chain. In addition to SiH groups within the chain, the Crosslinker 100 series features terminal SiH groups. These crosslinkers are essential components of polyaddition silicones. When working with two-component silicone formulations, it is crucial to maintain strict separation between Pt catalysts (e.g., Catalyst 500 series) and SiH crosslinkers to ensure proper performance.

- Application
When working with two-component silicone formulations, it must be ensured that Pt-catalyst (e. g. Catalyst 500 series) and SiH crosslinkers are kept strictly separated. In general, the composition must be selected so that the total formulation contains approximately a double molar excess of SiH groups as compared with vinyl groups.
