The present invention relates to compositions, which can be used for coating (e.g., painting) wiper blade rubbers to enhance durability, resistance to frictional forces, and/or other properties. In various embodiments, the coating compositions comprise nano-particle PTFE (Teflon®), polyurethane, and silicone resin in a solvent and/or liquid carrier, such as distilled water. The coating compositions may further comprise graphite, a carbon lubricant, and/or a water-based resin. Methods for forming a coating on a wiper blade rubber using the compositions of the invention are also provided.

1. A coating composition comprising: 3.5 to 15 total wt % of polytetrafluoroethylene (PTFE) particles;3.2 to 9.6 total wt % of polyurethane particles; and1.6 to 6.0 total wt % of polyhydromonomethylsiloxane oil or resin particles;in the presence of at least one solvent and/or liquid carrier, wherein all of said particles are present in the solvent and/or liquid carrier with a mean particle size of about 50 to 500 nm. 2. The coating composition according to claim 1, further comprising 5.0 to 25.0 total wt % of a thermosetting water-based urethane resin. 3. The coating composition according to claim 1, further comprising graphite or carbon black having a mean particle size of about 50 to 500 nm. 4. The coating composition according to claim 3, wherein said graphite or said carbon black is present at about 3.5 to 15 wt %, based on the total weight of the coating composition. 5. The coating composition according to claim 3, further comprising silver having a mean particle size of about 50 to 500 nm. 6. The coating composition according to claim 5, wherein said graphite or said carbon black is present at about 3.5 to 15 wt %, and said silver is present at about 0.16 to 0.5 wt %, based on the total weight of the coating composition. 7. The coating composition according to claim 1, further comprising silver particles having a mean particle size of about 50 to 500 nm. 8. The coating composition according to claim 7, wherein said silver particles are present at about 0.16 to 0.5 wt %, based on the total weight of the coating composition. 9. The coating composition according to claim 1, wherein said PTFE particles are present at about 7 to 8 wt %, and said polyhydromonomethylsiloxane oil or resin particles are present at about 2 to 3 wt %, based on the total weight of the coating composition. 10. The coating composition according to claim 1, wherein said PTFE particles have a particle size of about 250-350 nm, and said polyurethane particles and said polyhydromonomethylsiloxane oil or resin particles have a mean particle size of about 400 nm. 11. The coating composition according to claim 1, wherein said liquid carrier is distilled water. 12. A method for treating the surface of a wiper blade, comprising coating a wiper blade rubber with a coating composition of claim 1. 13. The method of claim 12, wherein said wiper blade rubber comprises natural rubber, butadiene rubber, styrene-butadiene rubber, EPDM rubber, chloroprene rubber, silicone rubber, or a combination thereof. 14. The method of claim 12, wherein said coating step comprises spraying said composition on said wiper blade rubber. 15. The method of claim 14, further comprising the step of heating said wiper blade rubber to a temperature of about 60 to 100° C. 16. The method of claim 12, further comprising the step of pre-treating said surface with a primer prior to said coating step. 17. A wiper blade made according to the method of claim 12. 18. An article comprising a substrate coated with the coating composition of claim 1.
