Quality Control

Our copolymer products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. We maintain strict control over monomer ratios, molecular weight distribution, and residual monomer content. Certificates of Analysis (COA) detailing key parameters such as solids content, viscosity, and glass transition temperature (Tg) 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, 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.
