Quality Control

Our Ethanol, 2-Amino-, Polymer With Methyloxirane And Oxirane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent properties such as amine value, viscosity, and moisture content. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing all relevant specifications to support your quality assurance protocols.

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product performance.
