Polyurethane dispersions for waterborne
adhesives
High-molecular-weight
polyurethanes form the basis for the Dispercoll® U product range
for aqueous dispersions.
Properties: The Dispercoll® U grades differ all in their
heat activation temperature. Their solids content is between 40
and 50 percent. Adhesives based on Dispercoll® U can be optimized
for the particular application through appropriate formulation.
The Dispercoll® U grades are based exclusively on aliphatic
raw materials, which are particularly resistant to yellowing.
Uses:
Dispercoll® U has proved itself above all in applications where
high forces and stresses occur and where initial strength is specified.
Furthermore, Dispercoll U is suitable for the production of bonds
with high flexibility and resistance to plasticizers and greases.
A typical area of application is in adhesives for laminating car
door liners.
