Abstract
A use of a lubricant comprising at least one reaction product of mono-di- and/or poly-isocyanate with unbranced and/or branced, unsaturated and/or saturated, alicyclic poly-amine with carbon numbers from 5 to 24, at least between at lease two elements, which are movable against each other.
Claims22
A method of lubricating a system comprising two elements moveable against each other, the method comprising applying a lubricant composition to the system, wherein the composition comprises:
- a reaction product of a mono-, di- or poly-isocyanate and an unbranched or branched, unsaturated or saturated, or alicyclic poly-amine with carbon numbers from 5 to 24, and
- a bismuth or alkylammonium salt of a carboxylic acid amide which is based on aliphatic unbranched, alicyclic or aromatic chains with lengths from 2 to 60 carbon atoms.
A method of lubricating a system comprising two elements movable against each other, the method comprising applying a lubricant composition to the system, wherein the composition comprises:
- a reaction product of a mono-, di- or polyisocyanate and an unbranched or branched, unsaturated or saturated, or alicyclic polyamine with carbon numbers from 5 to 24;
- and
- a magnesium, calcium, bismuth, or alkylammonium salt of a carboxylic acid amide which is based on aliphatic unbranched chains with lengths from 2 to 60 carbon atoms.
