Dry Lube (Dry Film Lubrication)

Dry lubricants are solid materials such as graphite, molybdenum disulfide, or specialized polymers applied to a metal surface to reduce friction without the need for liquid oils. In high-speed manufacturing, dry lubes are essential for preventing "galling" or metal-to-metal picking during intense forming operations. Unlike wet lubricants, dry films do not attract contaminants and can withstand the extreme pressures found in the roll bite. For galvanized products, dry lubes are often applied over a phosphate coating to provide a consistent coefficient of friction, ensuring smooth feeding through automated fabrication lines.
