Quality Control

Our Aluminium Dimagnesium Heptahydroxide is manufactured under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure consistent chemical composition, particle size distribution, and thermal performance. A Certificate of Analysis (COA) detailing purity, moisture content, and key physical parameters is provided with every shipment to guarantee compliance with your technical 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). This material is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent caking and degradation of performance properties.
