Molykote 33 Light Low Temp Grease

MOLYKOTE 33 Light Low Temperature Grease

Applications

MOLYKOTE 33 Light is intended for light-load applications where low-temperature performance, smooth movement, and material compatibility are important. Typical applications include:

• Rolling element bearings
• Plain bearings, bushings, and sleeves
• Control cables and light-duty control mechanisms
• Slides, guides, and tracks
• Plastic components and mechanisms
• Electric motors and electrical equipment
• Optical and photographic equipment
• Measurement and precision equipment
• Refrigeration and freezer equipment
• Light-load metal-to-metal and metal-to-plastic applications

Product Features

• Extreme low-temperature performance: Designed for applications requiring reliable lubrication at very low temperatures.
• Wide service-temperature range: Rated by DuPont for service from -73°C to 180°C (-99°F to 356°F).
• NLGI Grade 1: A softer grease consistency suitable for applications where a lighter consistency is preferred.
• Silicone-based formulation: Provides lubrication for a variety of metal, plastic, and elastomer applications.
• Lithium-thickened: Uses lithium soap as the grease thickener.
• Water resistant: Provides resistance to water exposure in appropriate applications.
• Oxidation resistant: Formulated for good resistance to oxidation.
• Plastic compatibility: Compatible with many plastics and suitable for applications involving plastic components.
• No solid lubricants: The formulation contains no solid lubricants.

MOLYKOTE 33 Light for Aircraft Maintenance

MOLYKOTE 33 Light can be useful in aircraft maintenance applications where a soft, silicone-based grease is appropriate for low-temperature or light-load service. Potential maintenance applications include control mechanisms, bearings, electrical equipment, slides, guides, and components incorporating plastics or elastomers.

For aircraft maintenance, always verify lubricant compatibility and application requirements against the applicable aircraft, component, or equipment maintenance documentation before use. MOLYKOTE 33 Light should not be substituted for a specified aircraft lubricant unless the applicable maintenance documentation permits the substitution.

MOLYKOTE 33 Light vs. MOLYKOTE 33 Medium

MOLYKOTE 33 Light and MOLYKOTE 33 Medium are both silicone-based, low-temperature greases, but they have different consistencies. MOLYKOTE 33 Light is NLGI Grade 1, while MOLYKOTE 33 Medium is NLGI Grade 2. The Light grade is therefore the softer consistency and may be preferred where the application calls for a lighter grease.

See MOLYKOTE DC33 Medium Low Temp Grease for the NLGI Grade 2 version.

Storage and Shelf Life

When stored in the original unopened container between 0°C and 40°C, DuPont states that MOLYKOTE 33 Light has a usable life of 60 months from the date of production.

For the actual expiration date of a specific container, refer to the date markings on the product packaging.
