  • Patent number: 9688937
    Abstract: The invention relates to a method for producing a stable boron solution with lubricating characteristics which is intended to be used preferably as an addition in the form of a concentrate/additive to a liquid, e.g. to a liquid fuel or a lubricant. The invention is achieved by the method steps of using a boron substance of pharmaceutical quality (1, 11), using a liquid as solvent, applying a mixing ratio between the boron substance and the solvent (3, 13) of preferably 1 g of boron per 15-25 liters of liquid, agitating the mixture for an initial predetermined period of time (4, 14), adding further liquid to dilute the solution (6, 15), the quantity of liquid being chosen such that a final user mixture reaches a concentration of between 20 and 30 ppm of boron (8), and further agitating the mixture (7, 16) for a second predetermined period of time so that the boron substance is completely dissolved in the boron solution, resulting in a boron solution which is stable over time.

    Abstract: This invention relates to a structural coating comprising a liquid carrier (e.g., paint), a borate-based additive, and a dynamic stabilization material. The borate-based additive provides corrosion protection through electrochemical binding of active surface corrosive sites, lubrication enhancement through the creation and re-supply to a surface where friction contact occasionally occurs of a weak slip lane crystalline material which may be a locally formed product utilizing local atmospheric humidity, and a material for reaction with an initiator to provide for freezing point depression during coating application. The dynamic stabilization material creates a balance of stabilized material for supply of corrosion protection product, lubrication reduction product, and freezing point depression product.

  • Patent number: 7811975
    Abstract: Improved boron-based metal working and machining fluids. Boric acid and boron-based additives that, when mixed with certain carrier fluids, such as water, cellulose and/or cellulose derivatives, polyhydric alcohol, polyalkylene glycol, polyvinyl alcohol, starch, dextrin, in solid and/or solvated forms result in improved metalworking and machining of metallic work pieces. Fluids manufactured with boric acid or boron-based additives effectively reduce friction, prevent galling and severe wear problems on cutting and forming tools.
