Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for your formulations. Key parameters such as hydroxyl value, acid value, viscosity, and solids content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specification results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flame. The product is moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture.
