Abstract: Release surfaces comprising extruded polymer-siloxane block copolymer mixtures are provided. At least one block of the copolymer is a polymer compatible with the bulk polymeric material, while a second block is polysiloxane. Coextruded release surfaces comprising two or more polymeric layers, including one layer of a polymer-siloxane block copolymer mixture, are provided. The release surfaces serve as release liners for pressure sensitive adhesive labels and tapes.

Abstract: A substrate is provided with a release surface by application of an emulsion of a vinyl-addition silicone system and catalyst therefor and a particulate component, preferably a resin. The vinyl addition silicone system is cured upon application of heat and removal of water.

Abstract: A process for forming organopolysiloxanes from hydrolyzable silanes and the resulting products are disclosed, characterized in that condensation of the silanes is carried out in the presence of a stabilizing amount of a weak organic base, such as quinoline, having an ionization constant in water no greater than about 1.times.10.sup.-7 at 25.degree. C. After hydrolysis of the silane, the resulting silanol is partially condensed to form the organopolysiloxane. During such condensation, the weak organic base provides improved stability to the organopolysiloxane solution against gelation prior to the time the organopolysiloxane is shaped and cured to a final thermoset form.

Abstract: Laminates of a metal base having a plasma or flame sprayed metal coating thereon, which coating comprises at least about 50% by weight of a transition metal, and including a layer of a solid film lubricant of effective lubricating amounts of a lubricating pigment dispersed in a polymeric binder on said flame sprayed or plasma sprayed metal coating. These laminates may be used at various glass contacting locations for handling glass in its process of manufacture.

Abstract: An improvement is provided in methods for conveying a charge, or gob, of formable glass along glass loading equipment, from the point of severance of the gob to the point where the charge of formable glass is discharged into a mold for forming; the improvement essentially resides in increasing the effective glass contacting life of lubricants, which have been previously employed on the glass loading equipment, by providing a support coating for the previously employed lubricants, which support coating comprises a transition metal in a major amount applied from a flame spray or plasma spray and presents an abrasion-resistant, rough surface profile upon which the previously employed lubricants are then deposited.
