Quality Control

Our production of this acrylic copolymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including tests for solid content, viscosity, glass transition temperature (Tg), and mechanical properties. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. Our quality system is designed to support formulations requiring compliance with relevant industry and regulatory standards.

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, ensure containers are properly sealed to prevent skin formation or changes in viscosity due to moisture or solvent loss.
