Abstract:
A lubricating coating which can prevent the occurrence of galling even when makeup is carried out with a high torque and which has excellent rust preventing properties is formed on the contact surfaces of a pin and/or a box of a tubular threaded joint. The lubricating coating contains copolymer particles made from particles of an acrylic-silicone copolymer with an average particle diameter of 10-50 μm dispersed in a highly viscous matrix made from a mixture of a rosin-based substance selected from rosin and its derivatives, wax, a metal soap, and a basic metal salt of an aromatic organic acid (such as highly basic Ca sulfonate).
Abstract:
An aqueous slicing fluid comprising (A) 0.01-20 wt % of a modified silicone is combined with abrasive grains to form an aqueous slicing slurry which has advantages of dispersion stability of abrasive grains, viscosity stability, and a higher machining accuracy.

Abstract:
A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.

Abstract:
The invention concerns a method for preparing a lubricating composition, characterised in that it comprises mixing two previously prepared oil-in-water emulsions (A) and (B): the prior emulsion (A) comprises: (a) at least a non-reactive linear polyorganosiloxane oil comprising per molecule at least 2% in number of organic substituents bound to the silicon atoms which are aryl, alkylarylene and/or arylenealkyl radicals; (b) at least a polyorganosiloxane resin bearing hydroxyl groups and comprising at least two different siloxyl units selected among those formula (R1)3SiO1/2(M), (R1)2SiO2/2(D), R1SiO3/2(T) and SiO4/2(Q), one at least of said units being a unit T or Q, R1 representing an organic substituent; (c) at least a crosslinking agent soluble in the silicone phase comprising at least two functions capable of reacting with the polyorganosiloxane resin(s) (b); (d) a condensation catalyst capable of catalysing the reaction of the constituent (b) with the constituent (c); (e) a surfactant; and (f) water; the prior emulsion (B) comprises: (anull) at least a reactive linear polyorganosiloxane oil comprising at least two OH groups per molecule, and the constituents (b), (c), (d), (e) and (f) mentioned above: each of the prior emulsions (A) and (B) comprises: 5 to 95 parts by weight of constituent (a) or (anull); 0.5 to 50 parts of constituent (b); 0.1 to 20 parts of constituent (c); 0.05 to 10 parts of constituent (d); for 100 parts of the sum (a)null(b)null(c)null(d) or (anull)null(b)null(c)null(d): the amounts of surfactant and water being sufficient to obtain an oil-in-water emulsion; and the weight ratio emulsion (A)/emulsion (B) ranges between 1.5 and 4.
Abstract:
The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

Abstract:
Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base. A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.
