Abstract
Disclosed are aqueous polyurethane compositions which contain at least one aqueous polyurethane dispersion, at least one compound blocked with isocyanate groups, at least one means for improving sliding behaviour, at least one surface-active and flow-control agent as well as optionally conventional bonding agents, dyes and/or pigments. Said aqueous polyurethane dispersions are useful for coating elastomers for obtaining a surface that has a very low coefficient of friction. Elastomer components that are coated according to the invention are useful for sealing window channels, for moveable glass components and/or as profiled joints in vehicle manufacturing, preferably in automobile manufacturing.
