Quality Control

Our production of this specialty acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for your critical formulations. Key parameters such as solid content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, ensure containers are properly sealed to prevent skin formation or changes in viscosity due to solvent evaporation or moisture absorption.
