Quality Control

Our Methacryloyl Chloride Polymer is manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance. Each lot is analyzed to confirm critical parameters such as degree of polymerization, reactive chloride content, and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and incompatible materials such as strong bases, alcohols, and amines.
