Treating elastomeric surface to improve slipperiness of e.g. windshield wiper blade brush in automobile, comprises applying powdery slipping agent on elastomeric surface, where hydrophobic substance is mixed with powdery slipping agent

摘要

Treating an elastomeric surface (I) to improve the slipperiness, comprises applying a powdery slipping agent (Ia) on (I), where a hydrophobic substance (Ib) is mixed with (Ia). An independent claim is included for a windshield wiper blade brush that is elastomeric treated by the process.
