Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical testing, including determination of hydroxyl value, acid value, viscosity, and color. Certificates of Analysis (COA) documenting these specifications are provided with every shipment and are available upon request 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); ensure containers are sealed after each use to prevent moisture absorption, which can affect product performance.
