Chemical Structure:

Description 

Vinyl fluorosilicone oil TPD‑FS8019 (CAS 68951-98-4) is a high‑performance polyfluorovinylsiloxane with reactive vinyl end‑caps on the fluorosilicone molecular chain.

The introduction of trifluoropropyl groups delivers outstanding oil resistance, solvent resistance, chemical inertness, good lubricity, low surface tension, and low refractive index. The reactive vinyl groups enable efficient crosslinking in addition‑cure systems, making this vinyl fluorosilicone oil ideal for high‑performance fluorosilicone rubber, sealants, and coatings.

Key Features

• EU REACH Registered
• Excellent oil, solvent, and chemical resistance
• High oxidation stability and long service life
• Low surface tension and low refractive index
• Reactive vinyl groups for addition curing
• Wide range of working temperature
• Low volatility and stable processing performance
