Quality Control

Our production of this advanced epoxy resin system adheres to strict quality management protocols, including in-process controls and final batch testing. Key parameters such as epoxy equivalent weight (EEW), viscosity, gel time, and thermal properties are rigorously monitored to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) detailing specific test results are provided with every shipment. We support compliance with relevant industry standards for composite and electronic materials.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive). Prolonged exposure to air and humidity must be avoided to prevent premature curing or changes in viscosity. Keep away from heat sources and open flame.
