一般特征

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.

储存条件

- Storage in original sealed Covestro container.

- Recommended storage temperature: 10 - 23 °C.

- Protect from direct sunlight, frost, heat and foreign material.

General information: 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. After extended storage time sedimentation can occur. The material can be proceeds without quality losses after homogenization.
