Quality Control

Our 4,4'-Methylenebis(N,n-Diglycidylaniline) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay, epoxide equivalent weight (EEW) determination, and impurity profiling, to ensure it meets precise customer and industry specifications. Certificates of Analysis (COA) documenting purity, viscosity, and other critical parameters 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, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product performance.
