Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, hydroxyl value, isocyanate content (NCO%), and molecular weight distribution are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with each shipment 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 a controlled room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
