Quality Control

Our production of this polymer intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and performance. Key parameters such as acid value, viscosity, and residual monomer content are rigorously monitored. Certificates of Analysis (COA) documenting full specifications are available for every shipment upon request.

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). Keep away from heat, sparks, and open flames. This material is compatible with strong acids and organic solvents but should be stored separately from strong oxidizing agents and bases.
