Quality Control

Our production of this epoxy resin intermediate adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Key parameters such as epoxy equivalent weight (EEW), amine value, viscosity, and color are rigorously controlled. Certificates of Analysis (COA) documenting all relevant specifications are provided with each shipment to support your quality assurance and regulatory compliance needs.

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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
