Quality Control

Our Polymer Of Butyl Methacrylate With 2-Ethylhexyl Acrylate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of molecular weight distribution, glass transition temperature (Tg), viscosity, solids content, and residual monomer levels. Certificates of Analysis (COA) detailing all 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, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain product stability.
