An all-natural multi-purpose cleaner, lubricant, and protectant composition includes 85-90 percent by weight Ethanol; 5-10 percent by weight D-Limonene: 1-5 percent by weight Lard; and less than 1 percent by weight Beeswax.

A structure forming, on the surface thereof, a liquid film for improving sliding property to a fluid substance, the liquid film containing solid particles of particle size of not more than 300 m that are dispersed therein. The structure exhibits further improved sliding property to the fluid substances due to the liquid film formed on the surface thereof, and can be favorably used as packing materials such as containers and lids.

A synthetic lubricant, cleaner and preservative composition and related methods for weapons and weapon systems, comprising: at least one isomer solvent; Alox 2100 calcium sulfonate; and at least one base oil selected from the base oil group consisting of: group I base oils; group II base oils; and group III base oils. Optional ingredients comprise mineral spirits, alpha-olefins, synthetic calcium sulfonates, fluoro-additives, and common moellen degras.

A structure including a base material formed in a predetermined shape, and a lubricating layer formed on the surface of the base material for improving sliding property to a fluid substance, the lubricating layer comprising a liquid and solid particles. The lubricating layer 3 formed on the surface of the base material exhibits very improved sliding property to the fluid substance and enables the structure to be favorably used as a packing material such as container and lid.

A water-based lubricating coating agent includes a water-soluble silicate (A) and at least one water-soluble inorganic salt (B) selected from a tungstate, a phosphate and a borate, wherein the water-soluble silicate (A) and the at least one water-soluble inorganic salt (B) are blended such that a solid content mass ratio (B)/(A) falls within a range of 0.7 to 25.

A coating composition for forming a lubricating layer (3) on the surface of a base material (1) formed in a predetermined shape so as to exhibit improved sliding property to fluid substances, the coating composition containing, as a dispersion medium, a liquid (5) that is a component constituting the lubricating layer (3), and the dispersion medium containing solid particles (7) dispersed therein as a component constituting the lubricating layer (3). The lubricating layer (3) formed by using the coating composition exhibits more improved sliding property to fluid substances. The coating composition, therefore, can be favorably used for forming the lubricating layer (3) on the inner surfaces of the packing materials such as containers and lids.
