Quality Control

Our production of this advanced polymeric resin adheres to strict quality management protocols. Each batch is characterized for critical parameters including epoxy value, acid value, viscosity, and thermal properties to ensure consistency and performance. 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, 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 may affect product performance.
