Quality Control

Our production of this polymeric resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, and color are rigorously monitored. A Certificate of Analysis (COA) detailing specific test results is provided with every shipment to support your quality assurance processes.

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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after initial use to prevent moisture absorption, which can affect product performance.
