Quality Control

Our production of this advanced epoxy phenolic resin adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical tests including epoxy equivalent weight (EEW), viscosity, gel time, and thermal stability analysis. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic nature, prolonged exposure to atmospheric humidity should be avoided to prevent moisture absorption, which can affect reactivity and performance. Keep away from heat sources and open flame.
