Quality Control

Our production of this epoxy hardener adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as amine value, viscosity, and color are rigorously tested. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing the specific properties of your lot. We support compliance with relevant industry standards for coatings and composites.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance. Keep away from heat, sparks, and open flame.
