OH-72 Hydroxy-Terminated Methyl Vinyl Silicone Oil
Silico® OH-72 Hydroxy-Terminated Methyl Vinyl Silicone Oil(CAS 67923-19-7) is a low-viscosity, reactive silicone fluid with hydroxyl end groups. It serves as a functional additive in silicone rubber compounding processes, particularly as a filler treatment agent and structure control additive. The presence of vinyl groups improves reactivity, while the hydroxyl termination enhances compatibility in crosslinking systems.
