This invention relates to a method of resurfacing an ice surface to reduce friction between the ice and an object gliding on the ice surface. The steps comprise mixing an effective amount of lubricant with water, coating the ice surface with the mixture, and allowing the mixture to freeze to form a new ice surface. In particular, the lubricant is derived from siloxane. In the preferred embodiment, the lubricant is a composition derived from polydimethysiloxane and copolyolamine. In the preferred embodiment, the ratio of water mixed with the lubricant is 300:1. This invention also provides for the use of the composition as an agent to reduce friction between an ice surface and an object gliding on the ice surface. In particular, an effective amount of the composition is mixed with water prior to applying the mixture to a surface upon which the ice surface is to form.

La présente invention fait état d'une méthode permettant de réduire la friction entre la glace d'une patinoire et un objet glissant sur cette dernière. La méthode comprend les étapes suivantes : mélanger une quantité suffisante de lubrifiant avec de l'eau; étendre le mélange sur la surface de la glace; et permettre au mélange de geler afin de former une nouvelle surface sur la glace. Le lubrifiant est plus particulièrement dérivé de siloxane. Le lubrifiant de la version privilégiée consiste en une composition dérivée de polydiméthylsiloxane et de copolyamide. Le rapport eau/lubrifiant de la version privilégiée est de 300/1. La composition de la présente invention peut aussi servir à réduire la friction entre la surface de la glace et un objet glissant sur cette dernière. Il suffit de mélanger une quantité suffisante de la composition avec de l'eau avant d'appliquer le mélange sur la surface sur laquelle la glace sera formée.
