    Abstract: A friction material member particularly useful in high load and temperature applications and a method for making the same are disclosed. The friction material member is made by preparing a mixture of sinterable metal particles, carbonaceous material, friction enhancers and curable polymeric resin; the mixture comprising at least about 50 percent by weight of metal particles and sufficient resin to coat and bond the metal particles, carbonaceous material and friction enhancers. The mixture is molded and the resin cured to form a piece in a solid preformed shape corresponding to the shape of the mold. Thereafter, the preformed piece is heated in a substantially oxygen free atmosphere for a time and at temperatures and pressures sufficient to fuse at least a portion of the metal particles into a sintered metal matrix. The preformed piece may be sintered to a metal backing plate during the heating step, or may be welded, brazed or soldered to the plate after heating. The resulting product may be classified as a hybrid friction material, i.e., being a cross between semi-metallic and sintered full metallic friction materials.

    Abstract: The invention concerns an improvement in the process for the production of dispersions of diorganopolysiloxanes and lubricant-acting inorganic silicates in water, whereby these dispersions contain, in addition to the above-mentioned substances, lecithin and nonionic emulsifiers, as well as solvents, ionic emulsifiers, lubricants other than inorganic silicates and diorganopolysiloxane, bactericides, fungicides, thickeners, antifoaming agents, rust inhibitors and dyes. The improvement is achieved by emulsifying the lecithin, nonionic emulsifier and water with each other before this mixture is mixed with at least 80% by weight of the diorganopolysiloxane contained in the finished dispersion, and, optionally, lubricants other than inorganic silicates and diorganopolysiloxanes. Furthermore, the invention concerns the application of the dispersions produced according to the invention as release agents, especially as inner tire release agents.
