A curing formulation operative as a lubricant is provided that has a plurality of silicone polymer precursors constituting a majority by weight of the formulation, each of the plurality of the silicone polymer precursors has a single curable moiety. A crosslinker is provided for reaction with the single curable moiety of each of the plurality of silicone polymer precursors to yield a thermoplastic silicone polymer having a majority by total weight of silicone polymer being comb- or branched-polymer form as the lubricant. A process of lubricating an interface is provide that includes the application of an aforementioned composition to the interface. Upon allowing sufficient time for the formulation to cure in ambient temperature conditions, a thermoplastic silicone polymer is formed having a majority by total weight of silicone polymer being comb- or branched-polymer.

Silicone lubricant

A substantially sulfur-free ammonium thiosulfate containing product can be produced by spray drying an aqueous solution containing ammonium thiosulfate and effective stabilizing amounts of both a carbonate component and a sulfite component under effective conditions to provide a substantially sulfur-free product. The carbonate component is selected from among ammonium carbonate or bicarbonate, an alkali metal carbonate or bicarbonate, or an alkaline metal carbonate or bicarbonate while the sulfite component is an ammonium sulfite or bisulfite, alkali metal sulfite or bisulfite, or an alkaline metal sulfite or bisulfite.
