Description

Zinc Octadecyl Phosphate is an organometallic compound that functions as a highly effective corrosion inhibitor and lubricant additive. Its unique structure provides excellent water repellency and anti-wear properties, making it a critical component for enhancing material durability and performance. This product is essential for industries requiring advanced metal surface treatment and friction reduction, such as lubricant manufacturing, metalworking, and protective coating formulation.

Application

• Lubricant & Grease Additive: Acts as an anti-wear and extreme pressure (EP) agent in industrial lubricants and greases, reducing friction and protecting metal surfaces under high load.
• Corrosion Inhibitor: Provides long-term protection for ferrous and non-ferrous metals in coatings, rust preventives, and metal treatment fluids.
• Metalworking Fluids: Incorporated into cutting oils, drawing compounds, and coolants to improve tool life and surface finish.
• Polymer Stabilizer: Used as a secondary stabilizer and lubricant in PVC and other polymer processing to enhance thermal stability and processing characteristics.
• Surface Modifier: Imparts hydrophobic properties to pigments, fillers, and powders, improving their dispersion in organic matrices.
• Fuel & Oil Additive: Serves as a detergent and anti-corrosion component in specialized fuel and engine oil formulations.

Quality Control

Our Zinc Octadecyl Phosphate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent purity, chemical composition, and performance characteristics. Certificates of Analysis (COA) detailing key parameters such as zinc content, phosphate content, and moisture level are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality.
