Quality Control

Our production of this unsaturated polyester intermediate adheres to strict quality management systems, ensuring batch-to-batch consistency for downstream polymerization processes. Key parameters such as acid value, viscosity, and hydroxyl value are rigorously monitored. A Certificate of Analysis (COA) detailing specific lot specifications is provided with every shipment to support your quality assurance protocols.

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); containers must be kept tightly sealed to prevent moisture absorption, which can affect reactivity and properties. Keep away from strong bases and incompatible materials.
