A refractory formulation containing an anhydrous solvent, an oleophilic rheology modifier and a refractory aggregate exhibits non-thermoplastic behavior, and remains plastic and formable at temperatures in the range of 10 degrees Celsius to 180 degrees Celsius. The oleophilic rheology modifier may effectively bind with the solvent to create a gel-like structure with organic solvents with moderate to high polarity. A phyllosilicate clay that has been treated with a quaternary fatty acid amine may be used as the oleophilic rheology modifier.

A friction control composition having high and positive frictional properties for sliding steel surfaces includes a water insoluble hydrocarbon that enables a reduced water content, a rheological additive, a freezing point depressant, a friction modifier, and a lubricant.

What is provided is a fluorine-containing ether compound represented by the following formula.
R.sup.1CH.sub.2R.sup.2CH.sub.2OCH.sub.2CH(OH)CH.sub.2OCH.sub.2R.sup.3CH.sub.2R.sup.4
(In the formula, R.sup.2 and R.sup.3 are perfluoropolyether chains, and R.sup.1 and R.sup.4 are terminal groups having two or three polar groups, in which individual polar groups are bound to different carbon atoms and the carbon atoms to which the polar groups are bound are bound to each other via a linking group having a carbon atom to which the polar groups are not bound).

In one aspect, the disclosure relates to lubricant compositions comprising an oil, a wax, or a combination thereof, wherein at least one of the oil or the wax comprises a very long chain fatty acid; and wherein at least one of the oil or the wax has been modified via a transgenic route to increase a concentration of the very long chain fatty acid relative to a reference concentration of the very long chain fatty acid in the oil or the wax without the modification. In a further aspect, the VLC FA can include one or more of eicosenoic acid, erucic acid, or nervonic acid.
