Quality Control

Our Naphthalenesulfonic Acid, Polymer With Formaldehyde And Urea, Sodium Salt is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance characteristics such as sulfonation degree, molecular weight distribution, and dispersing efficiency. A comprehensive Certificate of Analysis (COA) detailing physical, chemical, and performance specifications is provided with every shipment to guarantee it meets your application requirements.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent caking and degradation from atmospheric moisture. Keep away from strong oxidizing agents.
