The present invention relates to a coating for elastomeric linear profiles, where the coating comprises solid lubricant embedded into a polymeric matrix. It also relates to a wiper blade for windscreen wipers, comprising this type of coating, and also to a process for the production of an elastomeric linear profile coated according to the invention. The polymeric matrix with embedded solid lubricant is obtained by polymerizing, in the absence of polymeric binders, a mixture comprising the solid lubricant and low-molecular-weight crosslinking agent. In one embodiment, the matrix is obtained from the thermal polymerization of the low-molecular-weight crosslinking agent hexamethoxymethylmelamine. Examples of solid lubricants are graphite and HDPE.

Coating for elastomeric linear profiles, in particular windscreen-wiper blades, and process for production thereof

The invention relates to a wiper blade rubber and a method for the production thereof, in particular for a rail wiper of a motor vehicle, made from a formed, vulcanizable elastomer material the surface of which comprises a surface layer which is hydrophobic, with a contact angle with respect to water greater than 90&#xb0;, preferably greater than 120&#xb0;, and a surface structure with raised regions and/or recesses in the micrometer range.
