Product Description

 

Product Description

Siwin-VF21A is vinyl terminated in two ends of polydimethylsiloxane, the molecular is 300 - 300000 (synthesis different molecular in customers requirements). Because of formula structure, molercular is bigger, vinyl content is smaller. Except for with PDMS normal benefits,

it also has unique functions:

1.Two ends of vinyl group with strong active, it can addition reaction with hydrogen silicone oil under catalyst.

2.Comparing with PDMS, Siwin-VF21A has more better compatible with organic solvents, it more easy to use together with other organic materials.
