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 viscosity, acid value, hydroxyl value, and gel time are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with each shipment. We support compliance with relevant industry standards for raw materials used in coatings and composites.

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 product may be moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture.
