Quality Control

Our Hexasiloxane, Tetradecaethoxy- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and confirmation of key functional groups, to ensure consistency and compliance with agreed specifications. Certificates of Analysis (COA) documenting purity, identity, and physical parameters are provided with every shipment.

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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and degradation.
