Quality Control

Our production of this copolymer adheres to strict batch-to-batch consistency protocols, ensuring reliable performance in downstream formulations. Quality is verified through parameters including solid content, viscosity, glass transition temperature (Tg), and particle size analysis. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to guarantee compliance with your requirements.

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. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity.
