General Characterization
Bayhydur ultra 302 is a solvent-free, water-dispersible polyisocyanate based on hexamethylene diisocyanate (HDI).
Storage Conditions
Bayhydur ultra 302 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. Processability of this product can be adversely affected by contamination.
Recommended storage temperature is at room temperature (approximately 77°F/25°C).
The product is sensitive to moisture. Storage at higher temperatures will result in increase of color and viscosity. Due to the raw materials, the product may show visible turbidity caused by the cold. This turbidity occurs at approx. + 5 °C and is reversible when heated to room temperature. The product properties are not affected.
