Product Overview
Corrosion inhibitors and alkalinity reserve technologies help protect metal surfaces and maintain the chemical balance of metalworking fluids and industrial lubricant systems. By limiting rust and corrosion while supporting pH stability, these additives help preserve fluid condition and consistent performance throughout extended operating cycles.
Dover offers a broad portfolio of amine borates, fatty acid-based corrosion inhibitors, imidazolines, and water-soluble alkalinity reserves. Depending on the chemistry and formulation, these technologies can support rust protection, hard-water stability, surface adsorption, lubricity, and long-term fluid performance across water-based and oil-based systems.
Amine Borate Technologies
Amine borates provide corrosion inhibition and alkalinity support in metalworking fluid formulations. These technologies help protect ferrous surfaces while supporting fluid stability in challenging water conditions.
Dover's amine borate portfolio includes high-performance, cost-effective, and DEA-free options designed to support diverse formulation requirements.
Fatty Acid-Based & Imidazoline Technologies
Fatty acid-based and imidazoline corrosion inhibitors help protect metal surfaces through targeted rust protection and surface adsorption. Selected technologies also provide lubricity and support corrosion protection across oil-absorbing, oil-rejecting, and specialty fluid systems.
Dover offers corrosion inhibitor technologies for metalworking fluids, high-water hydraulic fluids, vanishing oils, and other applications where reliable surface protection is critical.
Alkalinity Reserve Technologies
Water-soluble alkalinity reserves help maintain fluid pH and support consistent performance as metalworking fluids are exposed to operating conditions, contamination, and extended use.
Dover's alkalinity reserve technologies can be incorporated into formulated fluids or sump-side packages to support pH stability and long-term fluid performance.
