Quality Control

Our production of this epoxy-amine adduct adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as amine value, epoxy equivalent weight, viscosity, and color are rigorously tested. A Certificate of Analysis (COA) documenting these specifications is provided with every 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 to prevent absorption of atmospheric moisture, which can affect performance.
