Divinyltetramethyldisiloxane(Cas 2627-95-4) Usage
| Summary | Divinyltetramethyldisiloxane, often abbreviated as DVTMDS, is a siloxane, meaning it contains silicon and oxygen atoms in a repeating chain, and it has two vinyl groups (H2C=CH-) attached to it. This unique structure makes it a versatile building block in various industrial applications, particularly in the production of silicone-based materials. |
| Roles | Divinyltetramethyldisiloxane is a vinyl-functional siloxane primarily used as a crosslinker or modifier in silicone formulations. It contains two reactive vinyl groups that participate in platinum-catalyzed hydrosilylation reactions with Si–H compounds, enabling the curing and crosslinking of silicone elastomers, coatings, and adhesives. Additionally, it serves as a key ligand in Karstedt’s catalyst, stabilizing and enhancing the activity of platinum in these reactions. Its low viscosity and compatibility with silicone systems also make it useful as a reactive diluent to fine-tune mechanical properties and processing behavior. |
