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, acid value, glass transition temperature (Tg), and molecular weight distribution are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment. We support compliance with global regulatory frameworks including REACH.

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 sources and open flame. For long-term storage, maintain under an inert atmosphere if the product is supplied in a solvent to prevent skin formation or polymerization.
