Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through a series of analytical tests including viscosity, solids content, glass transition temperature (Tg), and residual monomer analysis. Certificates of Analysis (COA) documenting all key parameters are available upon request to support your quality assurance protocols.

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. For long-term storage, ensure containers are properly sealed to prevent skinning or evaporation of volatiles.
