This invention relates to a method for the manufacture of fuser roll coatings for use in an electrostatographic copying machine. In accordance with this invention, room temperature vulcanizable (RTV) elastomeric materials are applied to fuser rolls by means of cross-head extrusion. The viscosities of the RTV material may be adjusted to suit the processing needs of cross-head extrusion. Upon leaving the cross-head extruder, RTV-coated fuser roll can be continuously turned to prevent sagging. In addition, the rotating coated roll may be passed through a hot air curing oven to produce a partial cure to increase the viscosity of the coating as well as to produce a skin on the coating which will stabilize the roll geometry. Additional curing and post-curing treatments may be provided thereafter as desir ed.
