Quality Control

Our production of this specialty copolymer adheres to strict quality management protocols. Each batch undergoes rigorous testing for key parameters including viscosity, hydroxyl value, acid number, and color to ensure consistent performance and batch-to-batch uniformity. Comprehensive Certificates of Analysis (COA) documenting all test results are provided to guarantee supply chain transparency and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. Under these conditions, the product is stable for extended periods.
