Quality Control

Our production of this epoxy adduct adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized using advanced analytical techniques to confirm key parameters such as epoxy equivalent weight, amine value, and viscosity. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 product performance.
