Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as solid content, viscosity, pH, and minimum film-forming temperature (MFFT) are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to support your quality assurance protocols.

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). For liquid forms, protect from freezing. Keep away from heat sources and open flame. Under recommended storage conditions, the product is stable for a minimum of 12 months from the date of manufacture.
