General Characterization

Dispercoll U 2849 XP is an anionic high-molecular-weight polyurethane dispersion.
Dispercoll U 2849 XP is a waterborne dispersion of a anionically modified polyurethane. It is an adhesives raw material for the formulation of adhesives for use in e.g. the furniture-, automotive- and shoe-industries. Due to the characteristic polymer properties Dispercoll U 2849 XP is suitable for adhesive applications with improved climate resistance.

Storage Conditions

Dispercoll U 2849 XP 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 result in a decrease of viscosity. 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.
