Quality Control

Our polyester-imide resins are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including viscosity, solids content, gel time, and thermal stability. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with relevant industry standards for electrical insulation materials.

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). Keep away from heat sources and open flame. The product may be moisture-sensitive; ensure containers are sealed after use to prevent absorption of atmospheric moisture.
