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 molecular weight distribution, glass transition temperature (Tg), viscosity, solids content, and monomer residue are rigorously monitored. Certificates of Analysis (COA) documenting full specifications are provided with every 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). Keep away from heat sources and open flame. Ensure containers are kept tightly sealed when not in use to prevent skin formation or changes in viscosity.
