Quality Control

Our production of this advanced silicone polymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. While specific grades may vary, quality is monitored through parameters such as epoxy equivalent weight, vinyl content, viscosity, and refractive index. 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect reactivity and performance. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
