Abstract
A lubricant varnish component and a lubricant varnish, for example, for coating elastomer profiles, are provided, wherein lubricant varnish component includes a polyurethane, a siloxane as well as a polyamide powder, a polyethylene powder or a solution of a polyamide. The lubricant varnish may additionally contain a curing agent, in particular an isocyanate-based curing agent. In addition, a first method for coating elastomers is proposed, wherein the proposed lubricant varnish is first applied in the form of a coating to an elastomer profile, and this coating then being dried and/or thermally crosslinked. Also, the proposed lubricant varnish, having or not having polyamide or polyethylene, may first be applied in the form of a first coat to the elastomer profile, and an alcoholic or aqueous solution of a polyamide in the form of a second coat or a polyamide powder or a polyethylene powder may then being applied to the first coat. The proposed lubricant varnish is suitable, for example, for the production of coated windshield wiper blades having a reduced coefficient of dry friction.
