Quality Control

Our Aminoethylaminopropylsiloxane-Dimethylsiloxane Copolymer is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including determination of amine value, viscosity, and refractive index. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee product integrity and traceability.

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/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption and contamination.
