63148-59-4 - brief introduction
Diphenyl (siloxane and polysiloxane) (also known as diphenylalkylpolysiloxane) is an organosilicon compound whose chemical structure contains phenyl and siloxane groups. Its properties are as follows:Physical properties:
Freezing point: usually a liquid with a low freezing point.
Solubility: It can be dissolved in organic solvents such as benzene, toluene, etc.
Chemical properties:
Stability: It has high chemical stability and is not easily decomposed at room temperature.
Inert: Under normal conditions, it does not react with water, acids, and bases.
Use of diphenyl (silicone and polysiloxane):
As a lubricant, its low surface tension and good lubrication properties are often used as mechanical and bearing lubricants to reduce friction and wear.
As an anti-adhesion agent, diphenyl groups (siloxanes and polysiloxanes) can form films at high temperatures, preventing adhesion between materials.
As a coating additive, its high temperature stability and optical properties can be used as a defoamer and stabilizer in coatings.
The preparation method of diphenyl (siloxane and polysiloxane) can be formed by combining phenyl with siloxane groups through the synthesis reaction of siloxane.
Avoid contact with skin. If it comes into contact with skin, wash it off immediately with soap and water.
Avoid inhaling vapors and maintain good ventilation during operation.
Avoid contact with eyes. If it comes into contact with eyes, rinse immediately with plenty of water and seek medical attention promptly.
When storing, it should be sealed away from sources of ignition and high temperatures, and placed in a place inaccessible to children.
