165454-24-0 - Introduction
3-(3-isocyyanatopropyl) Heptamethyltrisiloxane is an organosilicon compound. Its properties are as follows:
1. Appearance: colorless liquid
2. Boiling point: About 300 ° C
3. Density: about 1.02 g/mL
4. Solubility: soluble in organic solvents such as ethanol, toluene, xylene, insoluble in water.
This compound is mainly used as a component of silicone coatings, sealing materials and modifiers. It has high thermal stability and chemical stability, and it is not easy to decompose or react under regular temperature and pressure. As a sealing material, it can provide excellent moisture and gas barrier properties and protect the sealed object from the external environment. As a modifier, it can increase the flexibility, wear resistance and corrosion resistance of the material, and improve the anti-viscosity and anti-aging properties of the material.
A common method for preparing 3-(3-Isocyanatopropyl) heptamethyltrisilane is to react 3-propylisocyanate with Heptamethyltrisiloxane. The reaction is usually carried out under an inert atmosphere at a relatively low temperature and in the presence of an organic solvent. After completion of the reaction, the target product may be purified by distillation or other purification methods.
Regarding safety information, there are currently no specific safety data for this compound. However, as an organosilicon compound, appropriate safety measures should generally be taken. When in use, wear appropriate protective gloves and goggles to avoid contact with skin and eyes. If accidental contact occurs, it should be washed with plenty of water in time. During storage and use, keep away from heat sources, open flames and oxidants, and keep the container sealed. During the handling process, attention should be paid to explosion-proof and fire-proof safety measures, and treatment and disposal should be carried out in accordance with relevant laws and regulations.
