Modified silicone fluids are silicone fluids with additional functionality beyond the already fine properties of common dimethyl silicone fluid. This is achieved through the introduction of various organic groups. Depending on the organic group, fluids can be given properties of water-solubility, compatibility or reactivity with various organic materials, paintability, and greater lubriciry.
- Features of dimethyl silicone fluid
Water repellency Thermal oxidation stability Chemical stability Defoaming properties.
- Features gained through introduction of organic group
Paintability Solubility and dispersibility in water Compatibility or reactivity with organic materials Antistatic properties Flexibility Lubricity.
As shown below, the structures of modified silicone fluids are categorized into four major types, according to the position of the organic groups.
- Side-chain type
An organic groups are introduced into some of the side chains of the polysiloxane.
- Single-end type
An organic group has been introduced into one end of the polysiloxane.
- Dual-end type
An organic group has been introduced into both ends of the polysiloxane.
- Side-chain dual-end type
An organic group has been introduced into the side chains and both ends of the polysiloxane
