Quality Control

Our imidazole-modified epoxy hardener is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against stringent internal specifications for key parameters such as epoxy equivalent weight, viscosity, and active content. A Certificate of Analysis (COA) documenting purity and performance characteristics is provided with every shipment 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). Keep away from heat sources and open flame. This product is moisture-sensitive; ensure containers are sealed after use to prevent absorption of atmospheric moisture.
