Core Features
Chemical Stability & High-Temperature Endurance
At the heart of MOLYKOTE 3451 lies exceptional chemical stability, allowing it to resist degradation when exposed to a wide range of industrial chemicals, solvents, and fuels. Its high-temperature resistance is a standout trait, enabling seamless operation in environments where temperatures swing from extreme cold to intense heat, without losing lubricating efficacy or sealing integrity. This stability ensures that equipment remains protected even during prolonged exposure to harsh chemical atmospheres.
Superior Protective Properties
This fluorosilicone grease boasts outstanding water resistance, preventing moisture ingress that can lead to corrosion, rust, and component failure. It also features robust anti-oxidation capabilities, slowing down the aging process of both the grease itself and the equipment parts it protects. Additionally, its chemical corrosion resistance shields critical components from damage caused by aggressive substances, extending the overall lifespan of machinery.
Versatile Compatibility & Application Ease
MOLYKOTE 3451 exhibits excellent compatibility with a wide range of materials, including common sealing elements, rubbers, metals, and plastics. Its smooth consistency ensures easy application across various components, from small O-rings to large bearings, without clumping or uneven coverage. As a multi-functional lubricant and sealing solution, it eliminates the need for multiple products, simplifying maintenance routines and reducing operational costs.
Typical Uses
Aerospace Industry
In aerospace applications, this high-performance lubricant is indispensable for engines, fuel systems, and hydraulic systems. It reduces friction and wear in high-pressure, extreme-temperature environments, ensuring the safe and reliable operation of aircraft components that demand uncompromising performance.
Automotive Sector
Within the automotive industry, MOLYKOTE 3451 is ideal for lubricating and sealing O-rings, seals, and bearings in engines and transmission systems. Its ability to withstand high temperatures and resist automotive fluids ensures optimal protection, reducing maintenance frequency and enhancing vehicle durability.
Electronics & Chemical Industries
For electronics, it protects and lubricates sensitive connectors, switches, and relays, providing a barrier against moisture, dust, and chemical contaminants that can impair functionality. In the chemical and petrochemical sectors, it safeguards pumps, valves, and pipelines from corrosion and wear, maintaining efficiency in harsh chemical processing environments. It also serves heavy machinery and marine systems, offering reliable lubrication and corrosion protection in high-load, saltwater-exposed settings.
Precautions
Storage Guidelines
Store MOLYKOTE 3451 in a cool, dry environment away from direct sunlight and heat sources. Ensure the tube is tightly sealed after each use to prevent contamination and preserve the grease’s properties. Avoid storing near incompatible substances, such as strong oxidizers or solvents.
Application Safety
Wear appropriate personal protective equipment (PPE), including gloves and eye protection, during application to avoid skin and eye irritation. Do not mix with other lubricants or greases, as this can compromise performance and chemical stability. Apply only the recommended amount—excess grease may attract dust and debris, leading to increased friction.
Disposal Notes
Dispose of used tubes and excess grease in accordance with local environmental regulations. Do not release into waterways or soil, as improper disposal may cause environmental harm.
