ANTIFRICTION COMPOSITION

LUBRICANT COMPOSITION

MULTI-FUNCTIONAL PROTECTIVE COATING FOR ZINC-COATED STEEL SURFACES AND YOUR ALLOYS.

Antiadhesive and self-lubricating coating composition

The composition contains powdered polytetrafluoroethylene and a polyamide/imide resin in solution in an organic solvent. The composition may additionally contain a diluent and pigments and inorganic fillers. For coating metal surfaces or those made of materials withstanding a temperature of at least 220 DEG C, the composition is applied onto the previously degreased surface and the coating obtained is heated to a temperature of between 220 and 260 DEG C for 10 to 15 min to perform the polymerisation of the polyamide/imide resin. The coating thus obtained is free from pores and exhibits both good antiadhesive and self-lubricating properties and also a sufficient heat resistance and an excellent corrosion resistance.

SELF-LUBRICATING ANTI-FRICTION COMPOSITION.

Lubricant of magnetic recording media, magnetic recording media, and a magnetic recording device

In lubricant (5) of a magnetic recording medium made of conventional perfluoropolyether, one or more conductive high molecular compound is mixed. The conductive lubricant (5) prevents electric charge generated by frictional electricity from staying on the medium surface, and effectively prolongs the head-life by suppressing the break of the head element because of electric discharge between the disk medium and the head element. By employing the conductive lubricant, magnetic recording media and magnetic recording devices which are more reliable and durable can be realized.

Method of and compositions for reducing wear on surfaces subjected to frictional forces

A method and composition for reducing wear on surfaces subjected to frictional forces. The lubricating compositions can be applied in a carrier which may be organic or inorganic in nature. They function by providing a regime in which multimolecular layers are adsorbed onto the surfaces to be protected, thus enabling comparatively thick protective films to be built up on the surfaces subjected to frictional wear. The molecules having this property are essentially single or condensed unsaturated ring systems which comprise at least one six-membered unsaturated heterocyclic ring comprising at least one heterocyclic moiety which acts as a hydrogen acceptor and a hydrogen donor moiety. If substituents are present they should not create steric hindrance and/or render the molecule so basic or acidic as to alter the steric geometry of the molecule as to prevent the interaction of the active groups.

The lubricant is composed of a polyimide derived from 2,2-bis[4-(4-amino- phenoxy)phenyl]hexafluoropropane ("4-BDAF") and an aromatic tetracarboxylic acid (or dianhydride or ester thereof) containing fluorinated carbon.
