A crosslinkable polymer composition and a crosslinked polymer material including a metal member and a wiring harness. The crosslinkable polymer composition contains component A from which metal ion is released by heat, component B containing an organic polymer having a substituent capable of ionic bonding with the metal ion released from component A, and component C containing one or more acidic phosphate ester with a carbon number of 4 to 30. Assuming that the metal ion released from component A has a valence of +y and a content of the metal ion is m mol, the substituent contained in component B has a valence of −z and a content of the substituent is n mol, the acidic phosphate constituting component C has a valence of −x and a content of the acidic phosphate esters is 1 mol

g≥0.1 holds for g=(m.Math.y−l.Math.x)/(n.Math.z).

An anti-friction varnish includes at least one organic binding agent, at least one solid lubricant and at least one bonding agent for improving the adhesion of a polymeric sliding layer, which may be produced from the anti-friction varnish, on a substrate, wherein the at least one bonding agent includes a ligand, which connects the bonding agent to the organic binding agent or to the substrate.

The present invention provides a biodegradable formulation and its use as a surfaces restoring agent, said formulation allows a substantial savings when restoring the existing paint on different surfaces, since it mainly cleans and restores the surface or paint contaminated by the environment, damaged due to the sun and the processes of the different industries, in addition to being friendly to the environment, making it a useful technology in any industrial branch that involves cleaning and restoring large areas. It is worth noting that the modifications to the original formula were made to optimize the results in the different applications and improve its biodegradability.
