Chemical name: Methoxy Terminated Polydimethylsiloxane
RJ-241 is a special raw material for silicone compounding, which is mainly used as basic material for dealcoholized silicone sealant. It can effectively inhibit the viscosity peak caused by titanate catalyst, and improve the storage stability of the sealant.
Chemical name: Polydimethylsiloxane with trimethoxysilyl endgroups;
Siloxanes and Silicones, di-Me, (trimethoxysilyl)oxy-terminated
Cas No.: 142982-20-5
