Dispercoll U 58 is a waterborne dispersion of an anionically modified polyurethane. It is an adhesives 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 58 particularly well suited for heat activated bonding applications with high tack and good initial heat resistance.

Storage Conditions

Dispercoll U 58 should be stored in tightly sealed original containers and protected from direct sunlight, freezing, heat, and foreign materials. The product is sensitive to temperatures below +10°C. Temperatures below to + 10°C 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 15º-25ºC, temperatures higher than 30°C should be avoided.
