    Abstract: A method for using alkanolamine-carboxylic acid salts as a coating for friction materials which during use contact, at least part of the time, rustable metals. The method comprises contacting the friction material with an aqueous solution comprising at least about 0.05 weight alkanolamine-carboxylic acid salts being the reaction product of:(i) alkanolamine; and(ii) C.sub.4 -C.sub.20 carboxylic acid;and thereafter evaporating water from the aqueous coating on the friction material so as to leave the friction material with a coating comprising alkanolamine-carboxylic acid salts. Friction materials coated by above method are also claimed.

    Abstract translation: 使用链烷醇胺 - 羧酸盐作为摩擦材料的涂层的方法,其在使用期间至少部分接触生锈金属。 该方法包括使摩擦材料与包含至少约0.05重量的烷醇胺 - 羧酸盐的水溶液接触,所述链烷醇胺 - 羧酸盐是以下物质的反应产物:(i)链烷醇胺; 和(ii)C 4 -C 20羧酸; 然后从摩擦材料上的水性涂料中蒸发水,以便使含有链烷醇胺 - 羧酸盐的涂层留下摩擦材料。 还要求保护通过上述方法涂覆的摩擦材料。
