Quality Control

Our 2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethenylbenzene And Ethyl 2-Propenoate is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as solids content, viscosity, glass transition temperature (Tg), and mechanical properties to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting full specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
