Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of solid content, viscosity, pH, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee compliance with your formulation requirements and industry standards.

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 properly sealed to prevent skin formation or changes in viscosity.
