Quality Control

Our Poly(n-Methylvinylamine) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and functional performance. Standard parameters include assay, viscosity, and residual monomer content. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee compliance with your specifications.

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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and degradation.
