Methyl Hydrogen Silicone Fluid

What is Methyl Hydrogen Silicone Fluid (MH Silicone Fluid)?​​

Methyl Hydrogen Silicone Fluid (MH Silicone Fluid), also known as polymethylhydrosiloxane (PMHS), is a specialized silicone-based polymer widely recognized for its unique hydrophobic properties and versatility in industrial and consumer applications. With the ​CAS number 63148-57-2, this fluid is engineered to deliver exceptional water resistance and stability, making it a cornerstone in formulations ranging from personal care to industrial coatings.

​Key Properties of Methyl Hydrogen Silicone Fluid​

1. ​Chemical Composition​
   Methyl Hydrogen Silicone Fluid features a hybrid structure combining methyl and hydrogen siloxane groups. Its molecular formula, ​C₇H₂₂O₂Si₃, ensures compatibility with diverse substrates while maintaining flexibility and durability.
2. ​Physical Characteristics​
   • ​Appearance: Clear, colorless, and odorless liquid.
   • ​Viscosity: Adjustable from 10–40 cSt at 25°C, depending on formulation needs.
   • ​Thermal Stability: Operates effectively across a broad temperature range (-50°C to 200°C).
   • ​Flash Point: ≥120°C, enhancing safety in high-temperature applications.
3. ​Hydrophobic Performance​
   MH Silicone Fluid forms an invisible, flexible film on surfaces, repelling water and moisture. This property is critical in applications like waterproofing gypsum boards, textiles, and electronics.

​Applications Across Industries​

1. ​Personal Care & Cosmetics​
   • Used in skincare formulations to create water-resistant films, extending the efficacy of sunscreens and moisturizers.
   • Enhances the wearability of foundations and lipsticks by improving texture and spreadability.
2. ​Industrial Coatings​
   • Applied to glass, ceramics, and metals to prevent water ingress and corrosion.
   • Acts as a release agent in molding processes, ensuring smooth demolding of plastics and rubber.
3. ​Construction Materials​
   • Integral in waterproofing gypsum boards and plaster blocks, offering long-term protection against humidity.
4. ​Electronics​
   • Functions as an insulating fluid in circuit boards, protecting components from moisture and dust.
