Quality Control

Our production of this advanced polymer additive adheres to strict quality management systems. Each batch is characterized for critical parameters including equivalent weight, acid value, amine content, viscosity, and solids content to ensure consistent performance in your formulations. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment. We support compliance with relevant global standards for industrial chemicals, including REACH.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
