Quality Control

Our production of this advanced polymer adheres to stringent quality management protocols. Every batch is characterized for critical parameters including viscosity, acrylate equivalent weight, isocyanate (NCO) content, and color to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with each shipment to guarantee compliance with your formulation requirements.

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 strong acids, strong bases, and organic solvents. As a reactive chemical, it should be stored separately from heat sources and open flames.
