EG1 is widely used as a performance-enhancing additive in lubricant formulations. It improves thermal stability and reduces friction in engine oils, making it suitable for high-performance automotive and industrial applications. Its polar molecular structure allows strong adhesion to metal surfaces, enhancing wear protection under extreme pressure conditions. EG1 also acts as a dispersant, helping to keep contaminants suspended in oil, thereby preventing sludge formation and extending oil life. Additionally, it is employed in metalworking fluids to improve cooling efficiency and tool longevity during machining processes.
