Product Overview
Boundary lubricants and ester technologies help reduce friction and improve surface interaction under lubrication conditions where the lubricant film may not fully separate opposing metal surfaces. By supporting lubricity, film strength, and surface coverage, these additives help reduce metal-to-metal contact and improve performance across machining and metal-forming operations.
Dover offers a broad portfolio of ester technologies, oil-soluble boundary lubricants, and water-compatible lubricant technologies. Depending on the chemistry and formulation, these additives can support boundary lubrication, wetting, surface finish, and fluid compatibility across oil-based and water-based metalworking systems.
Ester Technologies
Polymeric and complexed esters provide high-performance boundary lubrication in demanding metalworking applications. These technologies support film strength and lubricity, helping reduce friction and improve metalworking performance across machining, stamping, and forming operations.
Dover's ester portfolio provides formulators with multiple chemistry options for balancing lubricity, fluid compatibility, and application requirements across machining, metal forming, and precision metalworking operations.
Oil-Soluble Boundary Lubricants
Oil-soluble boundary lubricants help reduce friction and support metalworking performance across precision machining, forming, and specialty lubricant applications. These technologies provide lubricity and surface-performance benefits where effective boundary lubrication is critical.
Dover's oil-soluble boundary lubricant portfolio provides multiple chemistry options for neat oils, soluble oils, metal-forming lubricants, and specialty metalworking applications where durable lubricity and surface protection are critical.
Water-Compatible Lubricant Technologies
Water-soluble lubricant technologies help deliver boundary lubrication and lubricity performance in soluble oils, semi-synthetics, and other water-based metalworking systems.
Dover's water-compatible lubricant technologies provide formulators with effective boundary lubrication for soluble oils, semi-synthetic, and synthetic metalworking fluids while supporting formulation balance, surface coverage, and fluid compatibility across water-based systems.®
Technical Overview
Boundary lubricants and ester additives are designed to reduce friction and improve surface interaction under boundary lubrication conditions where the primary fluid film may become insufficient. These technologies help support lubricity, film strength, wetting, and surface quality across metalworking and industrial lubricant applications.
Dover's portfolio includes ester technologies, oil-soluble boundary lubricants, and water-compatible lubricant technologies. Multiple chemistry platforms are available to help formulators balance boundary lubrication, fluid compatibility, surface performance, and application-specific requirements.
