Quality Control

Our Siloxanes And Silicones, (2-Hydroxy-1-Oxopropyl)Oxy Me, Hydroxy-Terminated is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, functionality, and performance. Certificates of Analysis (COA) detailing key parameters such as hydroxyl value, 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, well-ventilated area at room temperature (typically 15-25°C). This material is moisture-sensitive (hygroscopic); keep container tightly sealed when not in use to prevent absorption of atmospheric moisture which may affect product quality.
