ABSTRACT:
A lubricant composition for drawing metal wire comprises a lubricant which may be particulate, liquid or semi-liquid and discrete microcapsules having a liquid core, which enhances the wire drawing agent; in particular the liquid core may be an extreme pressure additive or an anti-wear additive; the liquid is released by rupture of the microcapsules in the die so that the liquid is released at the site where it is required.
