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, particle size, and minimum film-forming temperature (MFFT) are rigorously tested. Certificates of Analysis (COA) documenting all relevant specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 5°C and 30°C. Protect from freezing and prolonged exposure to elevated temperatures to maintain product stability and prevent coagulation or viscosity changes.
