ShinEtsu KF-354L is a polyether-modified silicone oil designed to deliver controlled flow, smooth surface appearance, and consistent tactile feel during formulation and application processes. It offers strong compatibility with organic systems, providing durability and spreadability in coatings, inks, and cosmetic formulations. During use, the fluid integrates uniformly into organic systems, allowing operators to achieve stable spreading behavior and predictable surface results without introducing processing instability. 

• Low Viscosity Control - ShinEtsu KF-354L has a kinematic viscosity of approximately 200 mm²/s at 25 °C, enabling rapid flow and uniform distribution in liquid systems. This viscosity level supports smooth incorporation during mixing without requiring elevated shear force. Consistent viscosity behavior across standard processing temperatures allows repeatable application quality in continuous and batch production lines.

  
  

• Surface Leveling - With a refractive index of approximately 1.463 at 25 °C, KF-354L integrates efficiently into organic coating matrices with minimal optical mismatch. This property supports reduction of surface tension gradients, improving leveling performance and reducing pinholes, streaks, and flow marks. Uniform surface appearance is maintained within standard coating thickness ranges.

  
  

• Density Balance - The specific gravity of approximately 1.10 at 25 °C supports stable dispersion in multi-component liquid formulations. This density alignment reduces sedimentation and phase separation during storage and processing. Predictable density behavior allows consistent formulation ratios in both short-term and extended production cycles.

  
  

• Thermal Stability - KF-354L polyether modified silicone oil maintains structural integrity under elevated processing temperatures commonly used in coating, printing, and finishing operations. The silicone backbone resists viscosity drift during thermal exposure, supporting stable flow behavior during drying and curing stages. This stability enables reliable processing outcomes in heat-assisted manufacturing conditions.

  
  

• Compatibility Range - The polyether-modified silicone structure allows KF-354L to blend effectively with a wide range of organic resins and solvents. Stable miscibility is maintained without precipitation or separation under standard formulation concentrations. This compatibility supports flexible formulation design across multiple system chemistries.

  
  

• Pigment Wetting - KF-354L polyether modified silicone oil improves pigment wetting efficiency by reducing interfacial resistance between pigment surfaces and binder systems. Low viscosity and balanced polarity support uniform pigment distribution during dispersion. This contributes to consistent color development and reduced agglomeration during production.

• Cosmetic Formulations - KF-354L polyether modified silicone oil is used in cosmetic surface coatings where controlled flow and smooth tactile finish are required. Its viscosity of approximately 200 mm²/s at 25 °C supports uniform spreading on substrates. This enables consistent appearance and touch performance in finished cosmetic products.

  
  

• Coating Industry - In industrial coating systems, KF-354L supports surface leveling and film uniformity during spray, roll, and curtain coating processes. Density and viscosity balance assist in maintaining consistent film thickness. This reduces surface defects and improves visual consistency in coated components.

  
  

• Printing Inks - KF-354L polyether modified silicone oil is applied in printing ink formulations to enhance wetting behavior and pigment dispersion. Compatibility with organic binders supports stable ink flow through printing equipment. This contributes to uniform print quality across extended production runs.

  
  

• Textile Finishing - In textile coatings and finishes, KF-354L supports smooth application and controlled fabric surface feel. Low viscosity enables even penetration and surface coverage. This results in consistent textile appearance after drying and curing processes.

  
  

• Adhesive Systems - KF-354L is incorporated into adhesive formulations to improve flow behavior during application. Stable viscosity and compatibility assist in achieving uniform adhesive layers. This supports consistent bonding performance and controlled surface finish in adhesive assemblies.
