The metallic composition having a metallic acrylate compound according to Formula I:
Claims27
A bearing comprising:
- a surface;
- and
- a self-lubricating surface coating composition deposited on said surface, said self-lubricating surface coating composition comprises a curable acrylate composition comprising a metallic composition, said metallic composition comprises a metallic acrylate compound according to Formula I:
A method of manufacturing a self-lubricating surface coating composition, said method comprising:
- forming a curable acrylate composition comprising a metallic composition, wherein said metallic composition comprises a metallic acrylate compound according to Formula I:
- combining a lubricant filler, a structural filler and a thixotrope with said curable acrylate composition to form a self-lubricating surface coating composition.
A self-lubricating surface coating composition comprising:
- a.) a curable acrylate composition comprising:
- a metallic composition, comprising a metallic acrylate compound according to Formula I:
- b. a lubricant filler selected from polytetrafluoroethylene, copper powder, molybdenum disulfide, boron nitride powder, graphite powder or combinations thereof;
- c. a structural filler selected from glass fiber, carbon fiber, microwool fiber or combinations thereof;
- d. a thixotrope selected from fumed silica, fine polytetrafluoroethylene powder or combinations thereof;
- and
- e. an initiator selected from benzoyl peroxide, cumene hydroperoxide, methyl ethyl ketone peroxide, or combinations thereof.
