General Characterization

Dispercoll U XP 2643 is an aqueous polyurethane dispersion.
Dispercoll U XP 2643 is an aqueous dispersion of an anionic modified polyurethane. It is a raw material for the formulation of adhesives for use in, for example, the packing, automotive, footwear and construction industries.
Because of the characteristic polymer properties Dispercoll U XP 2643 is suitable for bondings at roomtemperature and applications at low heat activation temperatures.

Storage Conditions

Dispercoll U XP 2643 should be stored in tightly sealed original containers and protected from direct sunlight, freezing, heat, and foreign materials. The product is sensitive to cold temperatures below +10°C. Freezing can damage the product irreversibly. Temperatures higher than 30°C should be avoided. Prolonged storage at higher temperatures may affect the product properties. 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.
