Quality Control

Our production of this specialty copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Every lot is tested against a comprehensive set of parameters including solids content, viscosity, pH, and particle size distribution. Certificates of Analysis (COA) documenting these results are provided with each shipment to guarantee the material meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Protect from freezing and extreme heat. Keep away from strong oxidizing agents. Under these conditions, the product has a typical shelf life of 12 months from the date of manufacture.
