Aerospace Solid Film Lubricants

Dry graphite is classified as a solid film lubricant because it forms a thin, adherent layer on metal surfaces that reduces friction without requiring a liquid carrier after drying. Once the quick-dry carrier evaporates, the graphite particles remain bonded to the surface, providing durable, long-lasting lubrication that won't run, drip, or migrate.

Yes. Zircon Industries' Dry Graphite Lubricant holds AAR M971-93 certification from the Association of American Railroads. It is also individually approved by major North American operators including CSX, Norfolk Southern, Canadian National, and Canadian Pacific, making it a trusted choice for railroad maintenance contractors across the U.S. and Canada.

The product is available in two application formats: aerosol spray cans (20 oz, 12 per case) for precise, targeted application on smaller components, and bulk liquid formats (1-gallon cases, 5-gallon pails, 55-gallon drums) for large-scale industrial operations that require high-volume coverage with consistent delivery.

No. The formula features a quick-dry, safe carrier that evaporates rapidly after application. Once dry, the graphite film stays firmly in place and will not run, drip, or migrate to adjacent surfaces. This makes it especially suitable for precision applications on railroad components, industrial gaskets, and aerospace assemblies where contamination must be avoided.

This dry graphite lubricant is designed for all metal-to-metal wear surfaces and is suited for a broad range of components including railroad switches, coupling hardware, engine parts, automotive and industrial gaskets, thread connections, autotrack chains and tracks, tie-down chalks, and hinges in both industrial and aerospace maintenance contexts.

Bulk purchasing options include 4x1-gallon cases, 5-gallon pails, and 55-gallon drums — ideal for high-volume industrial and railroad operations. Aerosol format is sold in cases of 12 cans (20 oz each). Pricing is available on request by contacting Zircon Industries at 800-547-4328 or via the DirectChem website contact form.
