General Characterization

Dispercoll U 8755 is an anionic high-molecular-weight polyurethane dispersion.
Dispercoll U 8755 is a raw material for the formulation of thermally activated adhesives for use in, for example, the furniture, automotive, shoe and construction industries. The characteristic rheology of the thermally activated polymer film makes Dispercoll U 8755 particularly well suited for use at elevated application and activation temperatures.

Storage Conditions

Dispercoll U 8755 should be stored in tightly sealed original containers and protected from direct sunlight, freezing, heat, and foreign materials. The product is sensitive to freezing. Freezing can damage the product irreversibly. Prolonged storage at higher temperatures may affect the product properties and possibly resulting in sedimentation or coagulation. Containers must be kept sealed and protected from direct sunlight as otherwise the evaporation of water will result in the formation of a non-redispersible polymer film. Recommended storage temperature is 10º-23ºC, temperatures higher than 30ºC should be avoided.
