Quality Control

Our production of Oxirane, Methyl-, Polymer With Oxirane, Mono(2-Ethylhexyl) Ether, Block adheres to a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent molecular weight distribution, hydroxyl value, and functionality. Certificates of Analysis (COA) detailing key parameters such as assay, water content, and pH are provided to guarantee the material meets your specific application requirements and internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance. Keep away from strong oxidizing agents.
