General Characterization
Dispercoll U 56 is an anionic high-molecular-weight polyurethane dispersion.
Dispercoll U 56 is a raw material for the formulation of thermally activated adhesives for use in, for example, the automotive, furniture, shoe and construction industries. Dispercoll U 56 is particularly well suited for applications with low thermal activation temperatures and is therefore particularly well suited for use on temperature-sensitive substrates.

Storage Conditions
Dispercoll U 56 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 5º-23ºC, temperatures higher than 30oC should be avoided.
