Quality Control

Our Soybean Oil, Polymer With Pentaerythritol, Phthalic Anhydride And Vinyltoluene is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as acid value, viscosity, solids content, and color to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) documenting these specifications are available upon request. Our production adheres to relevant industry standards to meet the demands of global coating formulators.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and organic solvents. As the product can be easily oxidized, it is recommended to store under an inert atmosphere or with a nitrogen blanket for long-term storage to maintain optimal properties. Keep away from heat, sparks, and open flame.
