Quality Control

Our production of this acrylic terpolymer adheres to strict Good Manufacturing Practice (GMP) guidelines where applicable. Every batch is subjected to a comprehensive suite of analytical tests to ensure it meets precise specifications for composition, molecular weight, viscosity, and residual monomers. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

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, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain product stability.
