Quality Control

Our production of this epoxy-functional silicone intermediate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including determination of epoxy equivalent weight, silicone content, viscosity, and purity, to ensure consistent performance and reliability. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance processes.

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/59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat and incompatible materials.
