Description :

Overview of Hexamethyldisiloxane

Hexamethyldisiloxane (HMDSO) is a widely used industrial organosilicon compound known for its volatility, chemical stability, and hydrophobic properties. It is typically supplied as a clear, colourless liquid with a mild odour and is valued for its Si–O–Si backbone structure with six methyl groups, which provides low surface tension and excellent compatibility in silicone-based systems.

A chemical used in industrial processes, Hexamethyldisiloxane is extensively used in the manufacture of silicone surface treatment systems, coatings, personal care intermediates, as well as advanced chemical formulations for industrial use in which the control of performance and consistency is vital.

Applications of Hexamethyldisiloxane

Silicone & Polymer Manufacturing

Hexamethyldisiloxane is widely used as an intermediate in silicone polymer manufacturing, helping chain termination and viscosity control. It is commonly processed alongside Hexamethyldisilazane, Chlorotrimethylsilane, and Silicon Dioxide in controlled silicone systems.

Surface Treatment & Coatings

Due to its hydrophobic nature, Hexamethyldisiloxane is applied in surface treatment and coating formulations, where it enhances water repellency and surface modification properties. It is often evaluated with Fumed Silica and Methyltrimethoxysilane in structured industrial formulations.

Solvent & Process Applications

Hexamethyldisiloxane is also used as a volatile silicone solvent in specialty industrial applications, offering a low toxicity profile and efficient evaporation characteristics under controlled conditions.

Safety & Handling Guidelines

• Place in a dry, cool, and well-ventilated space
• Beware of sparks, heat, and open flames
• Keep containers tightly closed and clearly marked
• Avoid inhalation of vapours and direct contact with skin or eyes
• Use protective gloves, goggles, and suitable industrial clothing
• Handle under controlled industrial conditions
• Dispose of waste and packaging according to regulatory guidelines
