Overview
SD15 is a sulfur-based industrial additive widely used to enhance the performance of lubricants. It is formulated to provide superior anti-wear and extreme pressure (EP) properties, making it ideal for demanding applications such as gear systems and metalworking processes. The additive works by forming a protective layer on metal surfaces, reducing friction and preventing wear under high loads. Its high sulfur content ensures effective performance in extreme conditions, extending the lifespan of machinery components.
Physical and Chemical Properties
SD15 is typically an amber to dark brown liquid with a density of approximately 1.1-1.2 g/cm³. It is soluble in mineral oils and synthetic base stocks, ensuring easy blending with various lubricant formulations. Key chemical properties include a high sulfur content, which contributes to its EP performance. The additive is stable under normal storage conditions but should be protected from direct sunlight and oxidizing agents to maintain its efficacy.
Main Applications
SD15 is primarily used in gear oils, where it provides critical protection against wear and pitting in high-load applications. It is also a common additive in hydraulic fluids, enhancing their performance under extreme pressure conditions. In metalworking, SD15 is added to cutting and grinding fluids to reduce tool wear and improve machining efficiency. Its versatility makes it a valuable component in industrial lubricants across multiple sectors.
Safety and Storage
When handling SD15, it is essential to wear protective gloves and goggles to prevent skin and eye contact. Inhalation of vapors should be avoided, and adequate ventilation is recommended in work areas. Storage should be in a cool, dry place, away from direct sunlight and oxidizing agents. Properly sealed containers are necessary to prevent contamination and degradation of the additive.
B2B Procurement Guide
When procuring SD15, buyers should verify the sulfur content and compatibility with their base oils. Reputable suppliers will provide technical data sheets and certificates of analysis to ensure product quality. Prices typically range from $5-10 per kilogram, depending on purity and supplier. Bulk purchases may offer cost savings, but buyers should ensure proper storage conditions to maintain product integrity.
