Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like molecular weight, viscosity, and hydroxyl value. Each lot is characterized using advanced analytical techniques including GPC, FT-IR, and titration methods. Certificates of Analysis (COA) detailing specific grade specifications are provided with every shipment. We support compliance with global regulatory frameworks including REACH and can provide documentation to assist with formulations targeting specific market approvals.

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). Keep away from heat sources and open flames. For long-term storage under warm conditions, inert gas (nitrogen) padding of containers is recommended to prevent skin formation or gelation.
