SiH crosslinker for formulating addition-cure RTV-2 silicones
Crosslinker 200 is a polydimethylsiloxane with SiH groups in the polymer chain and at both ends. You use it as a crosslinker when formulating addition-cure (platinum) RTV-2 silicones. Crosslinker 200 has a viscosity of 50 mPa·s, an SiH content of 3.2 mmol/g and a refractive index of 1.4030.
Key benefits
- SiH in the chain and at the ends: SiH groups along the polymer chain plus terminal SiH groups.
- Consistent quality: a uniform SiH content of 3.2 mmol/g.
- Low viscosity: at 50 mPa·s easy to mix in.
Typical applications
- ✓ Formulating addition-cure RTV-2 silicones
- ✓ Adjusting hardness and crosslink density of your own silicone formulations
Processing
- Determine the required amount from the SiH content and the vinyl content of your base polymer.
- Mix the crosslinker homogeneously into the component without platinum catalyst.
- Test every new formulation on a small scale first.
