Quality Control

Our Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Polymer With 1,3-Diisocyanatomethylbenzene is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot is tested for critical parameters including isocyanate content, viscosity, and moisture content to meet precise customer specifications. Certificates of Analysis (COA) documenting full test results are provided with every shipment.

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). This product is hygroscopic (moisture-sensitive). Containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature polymerization. Keep away from heat, sparks, and open flame.
