Usage

General Description

Methoxy terminated polydimethylsiloxane is a type of silicone polymer that consists of repeating units of dimethylsiloxane with methoxy groups at the ends. It is commonly used in various industrial and personal care products due to its properties such as water repellency, chemical inertness, thermal stability, and low surface tension. These polymers are often used as lubricants, surfactants, adhesives, and in the production of silicone sealants, elastomers, and coatings. Additionally, the methoxy termination provides improved compatibility with certain organic compounds and allows for functionalization with other chemicals, making it a versatile and valuable material in many different applications.
