Quality Control

Our production of this advanced polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including acid value, epoxy equivalent weight, viscosity, and molecular weight distribution. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global chemical management regulations.

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 material is moisture-sensitive (hygroscopic); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect reactivity and properties. Keep away from strong oxidizers, acids, and bases.
