Polyether modified silicone oil is a unique organic silicon non-ionic surfactant formed by graft copolymerization of polyether and dimethyl siloxane. The following is a detailed explanation of polyether modified silicone oil:
One. Chemical properties and structure
CAS number: 67674-67-3
Molecular formula: C11H27N3O3Si (there may be multiple isomers or variants)
Molecular weight: approximately 277.436
Density: Approximately 1.0 ± 0.1 g/cm3
Boiling point: 323.3 ± 21.0 ° C (at 760 mmHg)
Melting point: 0 ° C
Flash point: 149.4 ± 22.1 ° C
Other properties, such as vapor pressure, refractive index, etc., may vary depending on the specific product.
Two. Usage and Application
Coating additives: Polyether modified silicone oil is commonly used as an emulsifier, defoamer, wetting agent, and leveling agent in coatings. Through its unique molecular structure and interactions, it can significantly improve the leveling, smoothness, and scratch resistance of coatings.
Textile processing: can be used for soft and smooth processing of textiles, as well as as as as a textile softener, lubricant, etc.
Other industries: It is also a key component in the formulation of self emulsifying defoamers and delayed coking defoamers in the refining industry. In addition, it can also be used in various other industrial fields, such as as as a lubricant, brightening agent, leveling agent, etc.
Three. Performance customization and adjustment
The performance of polyether modified silicone oil can be customized by adjusting the number of silicone oil chain links, hydrogen content, ratio of polyether EO and PO, as well as the length of chain links and end groups, to meet the needs of different industries. For example, by adjusting the ratio of EO and PO units, a balance between hydrophilicity and hydrophobicity can be achieved, resulting in excellent defoaming and anti foaming properties.
Four. Storage and transportation
Storage conditions: It should be stored in a dry and cool place, avoiding contact with strong acids, bases, etc. There is a tendency for viscosity to increase or even crosslink when exposed to high temperatures, mixed with acidic or alkaline substances, or stored for too long.
Transportation method: Just follow the general cargo transportation.
In summary, polyether modified silicone oil is a high-performance organic silicon non-ionic surfactant with broad application prospects. Its unique molecular structure and properties enable it to exhibit excellent performance and effects in various fields such as coatings and textiles.
