Quality Control

Our production of this advanced epoxy modifier adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including amine value, viscosity, and equivalent weight to meet precise formulation requirements. A comprehensive Certificate of Analysis (COA) documenting these specifications is provided with every shipment 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 (15-25°C). Keep away from heat, sparks, and open flame. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption, which can affect performance.
