  • Publication number: 20240141204
    Abstract: 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.

  • Patent number: 11851576
    Abstract: 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.

  • Patent number: 11591551
    Abstract: A composition is provided for a non-aqueous foaming aerosol cleaner or lubricant. Foam builders, especially silicone glycol copolymers, are used to generate high density foam of the solvent-based formula. A cleaning product variant may be introduced via an air intake route for loosening deposits in an internal combustion engine. The high foam aerosol product dispenses easily without causing engine stalling. A process of lubricating a target substrate is also provided.

  • Patent number: 9637670
    Abstract: A coating composition for imparting a hydrophobic film on a target surface is provided that includes an oil of a silicone oil or a fluoropolymer oil or a combination thereof, a resin, and a dry lubricant. A solvent is present to form a solution of the oil and resin. A coating is imparted to an applicator that in turn can transfer the coating as a hydrophobic film. The coating composition is stable and able to impart hydrophobic film even after storage for several weeks at elevated temperature. The coating composition does so through the exclusion of synthetic waxes especially including silicone waxes. A kit is also provided that includes a wiper blade having the above coating composition applied along with 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.
