Quality Control

Our production of this advanced polyetheramine adduct follows a strict quality management system. Each batch is characterized using analytical techniques such as amine value titration, gel permeation chromatography (GPC), and infrared spectroscopy to ensure consistent composition and performance. A comprehensive Certificate of Analysis (COA) detailing key parameters like amine value, viscosity, water content, and color is provided with every shipment to guarantee it meets your specific formulation requirements.

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/59-77°F). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed when not in use to prevent moisture absorption. For long-term storage, consider using under an inert atmosphere (e.g., nitrogen) to minimize potential oxidation.
