Quality Control

Our production of this polymer adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, color, and solids content to ensure it meets the precise requirements of your formulation. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee traceability and compliance with your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Due to its chemical nature, it should be kept separate from strong acids, bases, and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Under these conditions, the product is typically stable for 24 months from the date of manufacture.
