Properties:
Hexamethyldisiloxane (HMDSO) is a volatile, colorless liquid with a mild odor. It is highly hydrophobic, chemically inert, and thermally stable. It is soluble in organic solvents (e.g., alcohols, ethers, hydrocarbons) but immiscible with water.
Applications:
- Silicone intermediate: Key precursor in the synthesis of silicone oils, resins, and rubbers.
- Water repellent: Used in coatings, textiles, and surface treatments for moisture resistance.
- Electronics: Acts as a cleaning agent, dielectric fluid, or protective layer in semiconductor manufacturing.
- Cosmetics & Pharmaceuticals: Functions as an emollient or carrier in personal care products.
- Industrial processes: Employed as a defoamer, lubricant, or heat transfer fluid.
Package & Storage:
- Packaging: 200L steel drum / customized packaging.
- Storage: Store in a cool, dry, well-ventilated area away from direct sunlight and oxidizers. Keep containers tightly sealed to prevent moisture absorption.
