ABSTRACT:
The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricating coating that is thermally cured at less than 200° C. or radiation-cured. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping, renewable lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide dry lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.
