Quality Control

Our production of this polymeric resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, and color are rigorously tested against internal specifications. A comprehensive Certificate of Analysis (COA) documenting all test results 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 product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect product performance.
