The present invention relates to a silicone wiper blade water repellent coating composition for a vehicle, a manufacturing method thereof, and a silicone wiper blade including the same capable of forming water repellent coating on a glass surface of the vehicle while reducing a hazing phenomenon which occurs when using a wiper silicone blade by adding an unused polyether siloxane additive to the inside of a water repellent coating agent in a specific ratio. The water repellent coating composition according to the present invention comprises: a substrate including a solid lubricant and a binder; a first mixture including first polyorganosiloxane, a polyether siloxane additive, and fluorine resin; and a second mixture including second polyorganosiloxane.
본 발명은 차량용 실리콘 와이퍼 블레이드 발수코팅 조성물 및 이의 제조방법, 이를 포함하는 실리콘 와이퍼 블레이드에 관한 것으로, 기존에 사용하지 않았던 폴리에테르 실록산 첨가제를 발수 코팅제 내부에 특정 비율로 첨가함으로써 와이퍼 실리콘 블레이드 사용시 발생하는 헤이징 현상을 저감시키면서 차량 유리 표면에 발수 코팅을 형성시킬 수 있다. 본 발명에 따른 발수코팅 조성물은 고체 윤활제 및 바인더를 포함하는 기재, 제1 폴리오르가노실록산, 폴리에테르 실록산 첨가제 및 불소수지를 포함하는 제1 혼합물 및 제2 폴리오르가노실록산을 포함하는 제2 혼합물을 포함한다.
