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 solids content, viscosity, pH, glass transition temperature (Tg), and monomer residue 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 temperatures between 15°C and 25°C (59°F and 77°F). Protect from freezing and extreme heat. Keep away from incompatible materials such as strong oxidizing agents. For specific storage recommendations related to different physical forms (e.g., emulsion, solid resin), please consult the technical data sheet.
