High-SiH crosslinker for compact crosslinking
Crosslinker 307 is a polydimethylsiloxane with pendant SiH groups along the polymer chain, but not at the ends. With an SiH content of 7.0 mmol/g the SiH share is relatively high, which allows compact crosslinking. In the platinum RTV-2 process this crosslinker cures without any by-product.
Key benefits
- High SiH content: 7.0 mmol/g for compact crosslinking.
- Pendant SiH groups: SiH groups along the chain, not at the ends.
- No by-products: cures in the platinum RTV-2 process without splitting off by-products.
Typical applications
- ✓ Formulating addition-cure RTV-2 silicones
- ✓ Harder or more densely crosslinked 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.
Points of attention
- ✓ This product is intended for the business market. For larger quantities or custom products, contact us at info@siliconesandmore.com.
