LS-PEG20 3-[Methoxy(Polyethyleneoxy)-Propyl]Trimethoxysilane
CAS NO. 65994-07-2
Silfluo LS-PEG20 is an MPEG-functional trimethoxysilane with approximately 6–9 ethylene oxide units. It is chemically described as 3-[methoxy(polyethyleneoxy)6-9]propyltrimethoxysilane.
The product contains a methoxy-terminated polyethyleneoxy segment and a trimethoxysilyl group. The polyethyleneoxy segment can increase the hydrophilic character of treated surfaces, while the trimethoxysilyl group can hydrolyze and react with hydroxylated inorganic surfaces such as glass, silica, metal oxides, ceramics and selected mineral fillers.
Because the polyethyleneoxy chain length is distributed across approximately 6–9 EO units, LS-PEG20 should be regarded as a technical-grade PEG silane mixture rather than a single low-molecular-weight compound.
LS-PEG20 can be evaluated as a hydrophilic surface modifier, dispersion support additive or functional silane for selected inorganic particles, glass surfaces, ceramic materials, waterborne systems and laboratory surface modification applications. Final hydrophilicity, dispersion stability, surface durability, protein adsorption behavior and compatibility should be verified in the target system..
