Quality Control

Our production of this advanced epoxy polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including epoxy equivalent weight (EEW), viscosity, and hydrolyzable chloride content to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant industry frameworks, and custom grades can be developed to meet specific customer 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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product performance.
