Monomethacryloxypropyl Terminated Polydimethylsiloxane
Monomethacryloxypropyl Terminated Polydimethylsiloxane is an asymmetric monofunctional free-radical reactive silicone macromonomer with flexible linear polydimethylsiloxane backbone. Only one molecular terminal carries reactive 3-methacryloxypropyl carbon-carbon double bond, while the other end is capped with inert trimethylsilyl group, which differs from dimethacryloxypropyl-terminated PDMS。Custom specifications are available upon customer request.

Storage Requirements
Store in tightly sealed containers in cool, dry warehouses at 2–25℃, shield from UV light and direct sunlight.
Do not co-store with peroxides, strong oxidants and strong alkalis to avoid premature gelation of methacrylate double bonds.
Keep packaging fully airtight to isolate air and moisture; standard shelf life is 6 months.
Stay away from high-temperature heat sources and open flames, maintain well-ventilated warehouse environment.
Mn：1000-1200
