Quality Control

Our production of this copolymer adheres to stringent Good Manufacturing Practice (GMP) guidelines to ensure batch-to-batch consistency and reliability. Each lot is characterized for critical parameters including acid value, hydroxyl value, viscosity, and glass transition temperature (Tg). A comprehensive Certificate of Analysis (COA) documenting these specifications is provided with every shipment, ensuring full traceability and compliance with your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C / 59-77°F). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. Ensure containers are kept sealed when not in use to prevent moisture absorption.
