Product Information

Heptamethyltrisiloxane, also known as HMTS or 1,1,1,3,5,5,5-Heptamethyltrisiloxane, is a low-viscosity linear hydrosiloxane with a Si-O-Si backbone and a reactive Si-H group.

It is mainly used as a functional silicone intermediate for preparing modified silicone fluids, silicone surfactants and specialty silicone additives. Due to its reactive hydrosiloxane structure, it is suitable for applications requiring further modification, good spreading performance, surface activity and formulation compatibility.

Typical Applications

• Intermediate for preparing modified silicone fluids and silicone surfactants.
• Used in the synthesis of polyether-modified trisiloxane and other functional silicone additives.
• Suitable for agricultural adjuvants, coatings, polyurethane additives and specialty formulations.
• Applied in surface treatment, wetting, spreading and formulation modification systems.
• Used as a reactive hydrosiloxane building block for customized organosilicon products.
