Quality Control

Our production of this advanced copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including monomer conversion, molecular weight distribution, and functional group content to ensure batch-to-batch consistency. Certificates of Analysis (COA) detailing specifications such as viscosity, hydroxyl value, isocyanate content, and glass transition temperature are provided and available upon request.

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 material is moisture-sensitive; ensure containers are sealed after use to prevent absorption of atmospheric moisture which can affect product performance.
