Quality Control

Our production of Triethoxy(Isocyanatomethyl)silane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure high purity and consistency. Certificates of Analysis (COA) documenting key parameters such as purity, isocyanate content, and specific gravity are available upon request, providing full traceability and compliance with customer specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen) to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and alcohols.
