Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical tests including viscosity, hydroxyl value, isocyanate content, and mechanical property assessments. Certificates of Analysis (COA) documenting key specifications are available for 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, and well-ventilated area at a recommended temperature of 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture which may affect product performance.
