The crosslinkers of the Crosslinker 100 and 200 series are polydimethylsiloxanes comprising SiH groups in the polymer chain. The crosslinkers of the Crosslinker 200 series additionally have terminal SiH groups. Both crosslinker types are used for addition curing silicones. Both series are available with different viscosity levels and SiH contents. Other SiH contents and viscosity levels can be delivered upon request.
Typical Applications
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. Further information about the formulation structure is available upon request.
