DUPONT™ MOLYKOTE® 557 Clear Silicone Dry Film Lubricant – 312 Gram Aerosol Can — Professional Grade Silicone Dry Film Lubricant

The DUPONT™ MOLYKOTE® 557 Clear Silicone Dry Film Lubricant – 312 Gram Aerosol Can is a high-performance silicone dry film lubricant manufactured by DuPont / MOLYKOTE and identified by part number 4150893. Engineered for demanding aerospace MRO, aviation maintenance, and industrial lubrication applications, this product silicone dry film lubricant reduces friction on plastics and rubber without staining or attracting dirt, providing a clean, dry lubrication surface. It is formulated for use on plastic components, rubber seals, metal surfaces, and mixed-material mechanisms requiring a clean, silicone-based dry film lubricant, and is compatible with plastic, rubber, metal, and composite surfaces in aerospace and industrial applications.

This lubricant is engineered to meet the performance demands of aerospace and industrial lubrication applications. Available in 312 Gram Aerosol Can format, the MOLYKOTE 557 delivers consistent lubrication performance across the demanding conditions encountered in aerospace and industrial service. Its formulation maintains a stable, adherent lubricating film that minimizes friction and wear, protects contact surfaces from galling and corrosion, and extends the service life of critical aerospace and industrial components.

The MOLYKOTE 557 is designed to remain in place under operating loads, vibration, and thermal cycling, providing reliable lubrication throughout the maintenance interval without significant migration or loss. This is particularly important for aerospace applications where component reliability, specification compliance, and long service intervals are essential. Using a specification-compliant lubricant ensures maintenance procedures meet OEM, regulatory, and quality system requirements.

Shake well before use. Hold the can upright and spray directly onto the surface from the recommended distance. Allow the lubricant to penetrate or the solvent carrier to evaporate before assembly or operation, as appropriate. Avoid contaminating the lubricant supply by using dedicated, clean applicators. Wear appropriate PPE including gloves and eye protection. Ensure adequate ventilation where applicable. Store upright in a cool, dry location away from heat, direct sunlight, and open flames. Do not puncture or incinerate the aerosol container. Refer to the full SDS and PDS for complete safety, handling, application, and disposal information.

From solid film lubricants for aerospace fasteners and actuators, to PTFE lubricants for chains and cables, to specialized fluids for thrust reversers and precision mechanisms, the DUPONT™ MOLYKOTE® 557 Clear Silicone Dry Film Lubricant – 312 Gram Aerosol Can provides the specification-grade performance and reliability that aerospace and industrial maintenance operations demand.
