Quality Control

Our production of this polymer adheres to strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent hydroxyl value, viscosity, and functionality. Certificates of Analysis (COA) detailing key parameters are provided to guarantee the material meets your formulation specifications and supports reliable, repeatable production outcomes.

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 / 59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from strong alkalis and incompatible materials.
