Foam control and corrosion resistance are critical performance requirements addressed by antifoam additives and corrosion inhibitors. Both are essential additive components across automotive, industrial and specialty lubricants.
Antifoam additives are typically silicone-based compounds that reduce surface tension, preventing air entrapment that compromises lubrication and heat transfer. Corrosion inhibitors, often overbased sulfonates or similar compounds, neutralize acids and form protective films on metal surfaces to prevent rust and corrosion.
Historically, these additives gained importance as lubricants encountered harsher service environments involving moisture, aeration and temperature extremes. As systems became more complex, additive chemistries evolved to offer better compatibility with modern base oils and longer service life.
Geographically, demand is strong across all regions. Asia growth is tied to industrial expansion and manufacturing. Europe emphasizes corrosion protection due to moisture-prone operating environments and regulatory oversight. North America remains a stable market with strong demand in transmission fluids and industrial oils.
Market trends highlight increasing use in specialty lubricants such as food-grade oils and advanced greases. Lubes’n’Greases reports rising interest in multifunctional additives that combine corrosion protection with load-carrying and wear resistance.
Foam and corrosion resistance additives will remain foundational as lubricants are expected to perform reliably in diverse and demanding global applications.
