General Characterization

Aqueous polyurethane dispersion. Dispercoll® U 2662 is a waterborne dispersion of an anionically modified polyurethane. It is an adhesive raw material for the formulation of adhesives for use in e.g. the shoe, furniture, or automotive industries. Its characteristic polymer properties make Dispercoll® U 2662 particularly well suited for heat-activated bonding applications with high tack and good hydrolysis resistance.

Storage Conditions

- Storage in original sealed Covestro container.
- Recommended storage temperature: 5-25 °C.
Temperatures higher than 30 °C should be avoided.
- Protect from direct sunlight, frost, heat and foreign material.
- General information: The product is sensitive to frost. Freezing can damage the product irreversibly. 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.
