Applications

This is a high-performance and highly reactive intermediate. It retains the general properties of methyl silicone oil such as smoothness, softness, gloss, heat resistance and weather resistance, and features the following characteristics and applications:

1. High reactivity of terminal vinyl groups. It can undergo addition reaction with hydrogen-containing silicone oil under catalyst action, and participate in various other chemical reactions.

2. Better compatibility with organic materials than conventional methyl silicone oil, facilitating blending with diverse organic substances.

3. Active double bonds enable easy reaction with polyurethane, acrylic and other organic materials.

4. Mainly applied in the preparation of liquid silicone rubber.
