General Characterization

Dispercoll U 2824 is an aqueous polyurethane dispersion.
Dispercoll U 2824 is a waterborne dispersion of an anionically modified polyurethane. It is a raw material for the formulation of adhesive dispersions. Dispercoll U 2824 contains carboxyl groups in the polymer chain that can be crosslinked with the polycarbodiimide from Desmodur® 2802 to produce high-quality adhesive bonds.

Storage Conditions

Dispercoll U 2824 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.
