Ice physics?

Not sure if this is the correct forum, as I started developing with UE4 a few days ago, but I need help adding ice physics. I’m using the 2d side scroller template. In the sprite settings I’ve editing the acceleration and friction to make it so I don’t instantly turn when I press left or right, but when I let go of the arrow key I instantly stop, instead of sliding a little bit.

Any help is appreciated.
