Quality Control

Our production of Phenol, Polymer With Benzaldehyde And (Chloromethyl)Oxirane adheres to strict quality management protocols. Each batch is characterized for critical parameters such as epoxy equivalent weight (EEW), viscosity, and chlorine content to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request, providing full traceability and compliance with your quality assurance 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). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. This material may be moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture.
