Quality Control

Our production of this advanced siloxane is governed by a rigorous quality management system. Each batch is characterized using advanced analytical techniques to ensure consistency in functional group content, molecular weight distribution, and viscosity. A comprehensive Certificate of Analysis (COA) detailing key specifications is provided with every shipment to guarantee it meets your precise formulation requirements.

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 at room temperature (15-25°C). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction.
