Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical formulation parameters. Each lot is characterized for key properties including acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is stable for extended periods. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption.
