Quality Control

Our 2-Methyl-2-Propenoic Acid Polymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters such as solids content, viscosity, pH, and glass transition temperature (Tg) to ensure consistent performance and batch-to-batch reliability. Certificates of Analysis (COA) documenting full specifications are available upon request 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 (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.
