General Characterization

Dispercoll U 2682 is an aqueous polyurethane dispersion.
Dispercoll U 2682 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 packaging, automotive, shoe or furniture industries. Its characteristic polymer properties make Dispercoll U 2682 particularly well suited for bonds with low heat activation temperatures.

Storage Conditions

Dispercoll U 2682 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. 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 5º-23ºC.
