18043-71-5 - Introduction

1,1,3,3-tetraisopropyldisilane (TIPDS for short) is an organosilicon compound. Its chemical formula is C12H28O2Si2, and its structure contains two silicon atoms and four isopropyl groups.

TIPDS is a colorless liquid with low surface tension, low viscosity and low volatility. It has good chemical stability and high temperature resistance, and can exist stably in the temperature range of -50°C to 200°C. In addition, TIPDS has a lower surface tension and can be applied to surface wetting and reduce the contact angle of droplets, thereby improving the coating performance of paints, glues, inks, etc.

TIPDS in electronics, optoelectronics, coatings, adhesives and other fields have a wide range of applications. For example, it can be used as silicone-based materials, silicone gels, high-temperature silicone gels, coating additives, and plastic modifiers. Because of its excellent heat resistance and chemical resistance, it is often used in high-performance applications such as electronic packaging and protective materials and optical coatings.

A common method for preparing TIPDS is to react hydrogen with trimethoxysilane to obtain trimethoxysilane hydride, and then react with isopropanol to remove methanol to obtain TIPDS. The specific preparation method can refer to the relevant literature of silicone synthetic chemistry.

Regarding safety information, TIPDS is an organic silicon compound, which is generally believed to have less impact on the human body and the environment. However, as with all chemicals, some safety precautions should be taken when using or handling TIPDS. Avoid skin and eye contact when contacting TIPDS, and take appropriate protective measures. During operation and storage, fire sources should be avoided and high temperatures should be avoided. It is recommended to operate under good ventilation conditions, and to store and dispose of the compound properly to avoid leakage and pollution to the environment.
