1. Used as the modifier of epoxy resin to improve the electricity performance and reduce the innerstress.

2. Used to synthesize copolymer block silicone oil, the finished products have the advantage non-yellowing,hydrophilic.

3. Used to prepare the demoulding agent to get the excellent demoulding result.

4. Used to increase the strength of the complex material and increase the interface binding force due to its good compatibility with the fillings and the fibers

5. Used as the broad-spectrum tackifier of addition type silicone rubber,it is also a good tackifier of aluminum glass.
