Description

Monoanisyl Terminated Polydimethylsiloxane, 7-8 Cst is a specialized organosilicon compound featuring a reactive mono-anisyl (methoxyphenyl) group at one terminus of a polydimethylsiloxane (PDMS) chain. This unique structure provides a valuable combination of silicone fluid properties with a reactive site for further chemical modification or crosslinking. It is engineered for applications requiring a low-viscosity, functional silicone intermediate with specific compatibility and reactivity profiles. Key industries that utilize this material include advanced material science, specialty adhesives and sealants, and performance coatings.

Application

• Reactive Intermediate for Silicone Copolymers: Serves as a key building block for synthesizing block and graft copolymers, introducing phenyl and methoxy functionalities into silicone networks.
• Surface Modifier & Coupling Agent: Used to modify surface properties of inorganic fillers (e.g., silica) or substrates, improving dispersion in organic matrices and enhancing adhesion.
• Specialty Release Coatings: Formulated into release liners where the reactive group allows for tailored adhesion levels and thermal stability.
• Lubricant & Process Aid Additive: Acts as a high-performance, functional lubricant in plastics processing or fiber manufacturing, reducing friction and improving flow.
• Adhesive & Sealant Formulations: Incorporated as a reactive plasticizer or modifier to adjust rheology, enhance compatibility with other resins, and influence cure characteristics.
• Pharmaceutical & Cosmetic Excipient: Potential use in topical formulations as a spreading agent or carrier, where its low viscosity and specific organic group are beneficial.
