Quality Control

Our production of Silicic Acid (H4Sio4), Tetraethyl Ester, Polymer With Bis(Acetyloxy)Dibutylstannane adheres to a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) detailing key parameters such as tin content, viscosity, and assay are available upon request to support your quality assurance protocols.

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 after initial use to prevent degradation from atmospheric moisture.
