摘要:
AN ABRASION RESISTANT, THERMOPLASTIC RESINOUS COMPOSITION IS PREPARED BY DISPERSING FROM ABOUT 1 TO ABOUT 100 PARTS BY WEIGHT OF A SOLID LUBRICANT IN ABOUT 100 PARTS BY WEIGHT OF A VINYL FLUORIDE HOMOPOLYMER OR COPOLYMER OF VINYL FLUORIDE AND VINYL ACETATE. USEFUL SOLID LUBRICANTS INCLUDE POLYTETRAFLUOROETHYLENE, FLUORINATED ETHYLENE PROPYLENE, MOLYBDENUM DISULFIDE AND TUNGSTEN DISULFIDE. THE COMPOSITION FORMS A DRY, ABRASION RESISTANT, COHESIVE LUBRICANT FILM ON A SUBSTRATE.
