Quality Control

Our production of this advanced organosilicon polymer adheres to strict quality management systems. Each batch undergoes comprehensive analytical testing, including determination of amine value, isocyanate content, viscosity, and purity, to ensure consistency and performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 2°C and 25°C. Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction. Isolate from sources of heat, moisture, and incompatible materials.
