Quality Control

Our production of this acrylic copolymer dispersion adheres to stringent quality management protocols. Every batch is tested against key performance parameters including solids content, pH, viscosity, particle size, and mechanical stability to ensure consistent performance and reliable supply. Comprehensive Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 5°C and 30°C. This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which can affect product performance. Protect from freezing.
