Quality Control

Our production of this chemical admixture follows a strict quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as sulfonation degree, molecular weight distribution, and dispersing efficiency are rigorously monitored. Certificates of Analysis (COA) documenting purity, solids content, pH, and specific performance tests are available for every batch 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent moisture absorption and caking. Keep away from strong oxidizing agents.
