Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, viscosity, acid value, and color are rigorously tested against internal specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each 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 (typically 15-25°C). Keep away from heat sources and open flame. This material is moisture-sensitive; ensure containers are sealed after use to prevent absorption of atmospheric moisture.
