Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical tests including viscosity, solids content, color, acid value, and functional group analysis. Certificates of Analysis (COA) documenting all key parameters are provided with every shipment. We support compliance with global regulatory frameworks such as REACH.

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. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption and skin formation.
