Diesel Antiwear Agent

Product Introduction
With increasingly stringent environmental regulations, higher requirements have been
imposed on diesel fuel quality, and sulfur content in diesel has been strictly controlled. With the
widespread use of low-sulfur and ultra-low-sulfur diesel, the issue of insufficient lubricity has
become increasingly prominent. In conventional diesel, polycyclic aromatics, nitrogen-containing compounds, aromatic
heterocyclic compounds, and other polar non-hydrocarbon components contribute significantly to
fuel lubricity. However, these natural lubricating components are largely removed during deep
hydrotreating and desulfurization processes. While clean diesel achieves reduced sulfur levels, its
inherent lubricating properties are also significantly diminished. As a result, engines operating on
low-sulfur diesel are more prone to wear and component damage, leading to reduced engine
service life. Diesel lubricity has therefore become a critical issue that cannot be ignored. SD-KM Diesel Anti-Wear Additive, developed by our company, exhibits excellent
compatibility and miscibility with diesel fuel. It shows strong affinity for metal surfaces and can
effectively adsorb onto them, forming a dense and stable protective oil film. This protective layer
prevents direct contact between metal asperities, significantly reducing mechanical wear and
effectively improving the lubricity of diesel fuel. SD-KM Diesel Anti-Wear Additive has no adverse effect on diesel cetane number, oxidation
stability, or low-temperature flow properties. It is fully compatible with diesel stabilizers and flow
improvers, with no antagonistic effects. The product demonstrates good adaptability to various
diesel fuels and provides outstanding anti-wear and lubricity performance.
