Quality Control

Every batch of our cationic vinylpyridine copolymer is manufactured under a strict quality management system. We provide comprehensive quality assurance, including control of molecular weight distribution, cationic charge density, and residual monomer content. A Certificate of Analysis (COA) detailing specific batch parameters is available upon request to ensure it meets your application requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture.
