MOLYKOTE 3452 Chemical Resistant Valve Grease is a white, fluorosilicone-based grease thickened with PTFE, developed for valve, seal, and bearing lubrication in chemically aggressive environments. It is engineered for long-term stability where exposure to solvents, fuels, and process chemicals would rapidly degrade conventional lubricants. MOLYKOTE 3452 maintains lubricating film integrity across a wide temperature range and is specifically selected for slow-moving, heavily sealed components requiring low volatility, material compatibility, and consistent torque behavior over extended service intervals.

• High Chemical Resistance - MOLYKOTE 3452 demonstrates resistance to most acids, fuels, solvents, and chemical vapors, maintaining grease structure and lubrication performance after prolonged exposure. Laboratory compatibility data confirms stable performance in contact with hydrocarbons, alcohols, and cleaning agents, supporting use in chemical processing equipment where lubricant degradation directly impacts seal reliability.

  
  

• Wide Temperature Stability - Designed for continuous operation from -30 °C to 230 °C, MOLYKOTE 3452 maintains consistent grease consistency and lubrication film thickness across thermal cycling. This temperature range supports cold-start valve actuation as well as elevated process temperatures without hardening, softening, or lubricant separation.

  
  

• Low Volatility Control - The fluorosilicone base oil exhibits low evaporation loss at elevated temperatures, reducing lubricant depletion in sealed systems. Low volatility behavior supports extended relubrication intervals in vacuum systems, enclosed valves, and sealed-for-life components where lubricant loss cannot be compensated during operation.

  
  

• Material Compatibility - MOLYKOTE 3452 is compatible with common plastics, elastomers, and sealing materials including silicone rubbers and O-rings. PTFE thickener chemistry minimizes swelling, embrittlement, or chemical attack, ensuring long-term sealing integrity in mixed-material assemblies.

  
  

• Oxidation Resistance - The grease formulation resists oxidative degradation under thermal and chemical stress, preventing viscosity breakdown and deposit formation. This stability supports predictable torque behavior in slow-speed valves and mechanical seals throughout long service cycles.
