Available in 210L nitrogen-sealed iron drums (240kg/drum) and 18L pails (20kg/pail). Store at 20-30 Degree C in a well-ventilated area. Protect from moisture and frost. If crystallization occurs below 15 Degree C, heat to 70-80 Degree C and agitate thoroughly before use. Shelf life: 6 months under recommended conditions.
Q1: What is the recommended storage condition for CDMDI-100L?
A: Store at 20-30 Degree C in a well-ventilated, dry indoor warehouse. Keep containers tightly sealed under nitrogen blanket when not in use to prevent moisture contamination.
Q2: Does CDMDI-100L crystallize during storage or transport?
A: Yes, crystallization may occur when the temperature drops below 15 Degree C. If crystallization happens, uniformly heat the product to 70-80 Degree C with thorough agitation before use. Avoid localized overheating, which can degrade product quality.
Q3: What makes CDMDI-100L different from standard MDI grades?
A: The carbodiimide-uretonimine modification gives CDMDI-100L a lower viscosity (25-60 mPa.s), liquid form at room temperature, and broader polyol compatibility. This allows it to serve multiple application lines with a single isocyanate, reducing inventory complexity.
Q4: How does moisture exposure affect CDMDI-100L performance?
A: CDMDI-100L reacts readily with atmospheric moisture to form insoluble polyureas, which can increase viscosity, reduce NCO content, and compromise final product quality. Always use nitrogen-sealed packaging and minimize open-air exposure during handling.
