Heptamethyltrisiloxane

Heptamethyltrisiloxane
Heptamethyltrisiloxane contains highly active silicon hydrogen bonds, it is the basic raw material for the synthesis of modified trisiloxane. Modified trisiloxane is a structurally specific surfactant with superior wetting and spreading properties that significantly reduces the surface tension of the system.
Typical Applications
  • Raw material for the synthesis of silicone surfactants
