Publication number: 20240141204Abstract: A coating composition for imparting water repellency from an elastomeric hydrophobic applicator of a wiper blade squeegee to a windshield is provided that includes a quaternary ammonium silane salt, a quaternary silicone polymer, a particulate dispersion; and a solvent. A wiper blade is also provided that includes a hydrophobic elastomeric wiper blade squeegee adapted to couple to a windshield wiper arm and to engage a glass windshield. A coating formed by the evaporation of the solvent from the aforementioned composition is present on the squeegee. A process of activating a windshield includes windshield being contacted by the wiper blade squeegee coated with the evaporated coating created from the aforementioned composition. The windshield is wiped under wet, dry, or a combination of wet and dry conditions with the wiper blade to impart a hydrophobicity of more than 60 degrees of water contact angle to activate the windshield.Type: ApplicationFiled: August 16, 2023Publication date: May 2, 2024Applicant: Illinois Tool Works Inc.Inventor: Jiafu Fang

Patent number: 11851576Abstract: A coating composition for imparting a hydrophobic film on a target surface is provided that includes a quaternary ammonium silane salt, a solvent, and a solid lubricant. The composition is stable and able to impart a hydrophobic film even after storage for several weeks at elevated temperature. The composition is non-absorbable or non-penetrative into an elastomeric applicator onto which the water repellant (WR) coating is applied, preserving the capability of transferring the WR ingredients of the coating from the wiper blade insert to a windshield on which the wiper blade insert is operated, even after the coated wiper blade insert has been aged for an extended period of time in storage. A wiper blade insert is also provided having the above composition applied and instructions for the securement of the wiper blade to a vehicle to impart the hydrophobic film to a vehicle windshield contacted by the wiper blade insert.Type: GrantFiled: May 15, 2020Date of Patent: December 26, 2023Assignee: Illinois Tool Works Inc.Inventor: Jiafu Fang
