Vinyl Ethyl Silicone Oil IOTA 20566 is a reactive organosilicon fluid containing vinyl functional groups along a flexible ethyl-modified polysiloxane backbone. The vinyl groups are highly active in hydrosilylation (Si–H addition) reactions, making the product a key intermediate in addition-cure silicone systems.
Compared with conventional vinyl silicone fluids, the ethyl-modified structure improves flexibility, compatibility, and low-temperature performance, while maintaining strong reactivity in platinum-catalyzed curing systems.
The product is mainly designed for silicone hydrogen addition (hydrosilylation) systems, where it acts as a reactive component for network formation, property tuning, and performance optimization.

Vinyl Ethyl Silicone Oil is widely used as a vinyl-terminated or vinyl-functional component in addition-cure silicone rubber.
In platinum-catalyzed systems, the vinyl groups react with Si–H functional silicone oils or crosslinkers to form a three-dimensional silicone network.
Typical roles include:
It helps achieve:
In LSR and high-performance silicone elastomer systems, this product is used to fine-tune processing and final mechanical properties.
It contributes to:
Because of the ethyl-modified structure, it provides a softer and more flexible cured network compared with conventional vinyl methyl silicone systems.
In hydrosilylation-based silicone gel systems, Vinyl Ethyl Silicone Oil is used to build soft, stable crosslinked networks.
Typical applications:
It helps achieve:
In Si–H addition modification systems, this product is used to introduce flexible vinyl-containing segments into silicone resins or hybrid materials.
Functions include:
It is especially useful in systems requiring a balance between rigidity and flexibility.
Vinyl Ethyl Silicone Oil can also be used to adjust the reaction rate and curing behavior in hydrosilylation systems.
By adjusting vinyl content and molecular structure, it helps control:
This makes it a functional tool for formulating precision addition-cure silicone systems.
The core value of Vinyl Ethyl Silicone Oil IOTA 20566 lies in its role as a reactive vinyl component in Si–H addition systems. It is not only a structural building block for crosslinked silicone networks, but also a key modifier for flexibility, processing behavior, and final mechanical performance.
It is especially suitable for:
