Metaflux 70-07/400 ml Open Gear and Chain-Spray 
is designed for outdoor cranes and other machines used in seaports, in coal-mining, sewage treatment plants, for the handling of liquid manure, for machines exposed to thawing salt during winter time etc. - and there for the lubrication of slow moving parts. The product sticks well to the surfaces - it may not be easily washed off. Its lubricating effect was tested in the range of -20 degrees Centigrade up to +80 degrees Centi-grade. It is most probably also effective with higher and lower temperatures. 
N.B.: Do NOT use on chains made of plastics.

Metaflux 70-07 Open Gear and Chain-Spray 
is also successfully used indoors: At a fire-galvanizer it is used to lubricate parts near to the drying stove and to protect chains and wire-ropes passing over the acid bath against corrosion by the warm aggressive atmosphere.
