industrial Grade Moisture Resistant Dielectric Sealant Paste is a specialized electrical protection material designed for insulation, sealing and protection of electrical components in demanding industrial environments. With reliable dielectric performance, excellent moisture resistance and stable protective properties, it helps manufacturers improve electrical reliability and extend the service life of sensitive connections and components.

• Dielectric Strength - KS-64F is formulated as a silicone dielectric insulating paste with stable electrical insulation performance supported by a viscosity of approximately 1,500 mm²/s at 25 °C, allowing the material to remain in place around conductive components while maintaining consistent insulating separation under operational conditions.

  
  

• Thermal Stability - The paste maintains physical consistency and insulating behavior across wide temperature ranges, supported by a refractive index of approximately 1.410 at 25 °C, indicating a stable silicone network that resists breakdown during prolonged thermal exposure.

  
  

• Moisture Resistance - With a specific gravity of approximately 1.05 at 25 °C, KS-64F forms a dense, continuous barrier that limits moisture penetration, supporting long-term stability of electrical interfaces in humid or condensation-prone conditions.

  
  

• Paste Consistency - The white paste appearance and controlled rheology allow uniform coverage on uneven surfaces, supported by its measured viscosity profile at 25 °C, which helps prevent flow separation or thinning during application and service life.

  
  

• Material Compatibility - The silicone-based formulation remains chemically stable when in contact with common metals and insulating materials, with physical properties at 25 °C indicating low reactivity and stable interface behavior during prolonged contact.

  
  

• Long-Term Stability - Packaging in 1 kg containers supports controlled storage and handling, while stable physical parameters at 25 °C contribute to consistent performance over extended storage periods without phase separation or property drift.
