Quality Control

Our production of this polyurethane polymer adheres to rigorous quality management systems. Each batch is characterized for critical parameters including isocyanate (NCO) content, viscosity, and hydroxyl value to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these specifications are available upon request. We support compliance with relevant industry standards for polymer production.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Protect from moisture to prevent premature reaction or viscosity changes. Keep away from heat sources and open flame.
