Quality Control

Our production of this advanced polymeric resin adheres to strict quality management systems, ensuring batch-to-batch consistency for critical formulation parameters. Key characteristics such as acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with global regulatory frameworks, including REACH.

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). Keep away from heat sources and open flame. This product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption, which can affect performance.
