一般特征

Anionic high-molecular-weight polyurethane dispersion.
Dispercoll® U XP 2702 is an adhesive raw material for the formulation of thermally activated adhesives. It can be combined with deactivated IPDI trimers for the formulation of latent-reactive polyurethane dispersion adhesives. Dispercoll® U XP 2702 exhibits greater reactivity with the isocyanate groups of the IPDI trimer than does Dispercoll® U 56.

储存条件

- Storage in original sealed Covestro container.

- Recommended storage temperature: 5 - 23 °C, temperatures higher than
30 °C should be avoided.

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

General information: The product is sensitive to frost. Freezing can damage the product irreversibly. Temperatures higher than 30 °C should be avoided. Prolonged storage at higher temperatures may affect the product properties and possibly resulting in sedimentation or coagulation. 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.
