Quality Control

Our brominated epoxy resins are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot is analyzed for critical parameters including bromine content, epoxy equivalent weight (EEW), viscosity, and thermal properties. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We support compliance with global standards such as REACH, RoHS, and UL for flame-retardant materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Under these conditions, the product is stable for extended periods.
