PCT No. PCT/CA95/00658 Sec. 371 Date Jul. 14, 1997 Sec. 102(e) Date Jul. 14, 1997 PCT Filed Nov. 23, 1995 PCT Pub. No. WO96/15857 PCT Pub. Date May 30, 1996A process of coating a heat-conductive strip article, e.g. aluminum or aluminum alloy strip used in the automotive industry, with a solid wax-like coating material, preferably a wax-type lubricant. The process involves heating a solid wax-like coating material that melts in a temperature range of about 30 to 100 DEG C. to form a melt having a viscosity in a range of about 50 centipoise or less and flowing the melt onto a moving surface of the strip article through an elongated slot in a movable coating head having an extended surface adjacent to the slot to form a coating layer on the article. The coating head is pushed towards the surface of the strip article as the melt is flowed as a coating onto the surface from the slot to reduce a coating thickness by pressing the extended surface of the coating head onto the coating as the coating is formed. The process allows a coating of a wax-like material to be formed to a desired thickness and yet allows the wax-like material to solidify shortly after application to the strip article so that the strip can be coiled without providing a cooling run of undue length or a special cooling devices.
