Quality Control

Our production of 2-Propenoic Acid, Ethyl Ester, Polymer With n-(1,1-Dimethylethyl)-2-Propenamide And 1-Ethenyl-2-Pyrrolidinone adheres to stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent molecular weight distribution, monomer content, viscosity, and solids content. Certificates of Analysis (COA) documenting full specifications are provided with every shipment to guarantee traceability and compliance with your technical requirements.

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, consider a nitrogen atmosphere to prevent oxidation. Keep container tightly sealed when not in use to prevent moisture absorption and skin formation.
