    Abstract: Seize is prevented between metal surfaces exposed to high temperature and corrosive gases by an antiseize coating layer. The coating comprises per 100 weight parts, about 10-30 parts chemically inert anti-seize particles that have a fusion point above about 100.degree. C. and are in the size range of from about 2-100 microns; about 5-25 parts of a polymeric binder resin that is adherent to metal surfaces; and the balance, a volatile solvent for the resin. The liquid coating is applied by suitable means, and dried by evaporating the solvent. At least a layer of the particles remains dispersed in the dried resin and provides the coating with its antiseize properties.

    Abstract: A fluidic fluid composition containing lamellar micelles and which exhibits retro-viscous properties at noncryogenic temperatures is composed of 7.00-7.35% of a surfactant (preferably petroleum sulfonate having an average equivalent weight of 350-525), 50.00-54.00% of liquid hydrocarbon, 24.80-28.00% of water and optionally up to 13.00-13.95% of a cosurfactant (preferably an alcohol containing 1-20 carbon atoms) and/or electrolyte (preferably inorganic salt). The micelles within the composition must have an axial ratio of at least 3.5. The composition is substantially optically clear, phase stable, birefrigent, and the flow properties are such that substantially large increases in flow rates, e.g. 20-fold, can be realized at very small pressure increases, e.g. 5%. Additional additives to impart desired properties can be included with the composition.
