The present invention provides a method and kit for the treatment of surfaces, such as the skin surface of a user, to impart hydrophobic characteristics upon the surface. The treatment of surfaces to impart hydrophobicity protects equipment, personnel, and animals from the effects of aqueous solutions such as water, toxic slurries, concrete, acids and bases.

An athletic chalk comprising plaster of Paris, magnesium carbonate and activated charcoal, having relative proportions of materials of approximately 71-75% plaster of Paris, 19-23% magnesium carbonate and 10-2% activated charcoal, and a method for producing same.

A traction enhancing aggregate is provided comprised of a body with a side having a top and bottom with each having three or more protruding conical masses with axes positioned about a circular centerline and made from moldable material capable of being delivered by hand or traction enhancing system to a lower surface such as ground to provide an increased coefficient of friction between an upper surface such as a shoe or tire and a lower surface.

A friction material which comprises a fibrous base, a binder, a lubricating material, an organic filler, and an inorganic filler, the friction material having a copper element content of 0.5 wt % or less with respect to the whole friction material, wherein the lubricating material comprises graphite having an average particle diameter of 10.0 m or smaller and the inorganic filler includes barium sulfate, which comprises small-diameter barium sulfate having an average particle diameter of 1.5 m or smaller and a purity of 95.0% or higher.

A process for manufacturing a friction material and an inorganic liquid binder for use in manufacture of friction materials. The process for the friction material makes use of a liquid binder that provides the performance of process steps with significant reduction in temperature, pressure and manufacturing time, making the process more energy efficient. The process also includes manufacturing a liquid binder that allows the use of different types of inorganic precursors with crystalline and/or amorphous features, through a mechanical activation process of the inorganic precursor. The process pertains to the fields of chemical engineering, mechanical engineering, materials engineering, focused on the area of friction materials for vehicle brake systems.

A traction enhancing composition that increases traction on all types of footwear and other surfaces is provided. Within a composition suitable for application to the surface of any footwear sole in liquid form, by pouring the composition into the bag supplied, and then placing the footwear into the composition for up to 12 hours. Alternately, by applying to composition to a horizontal surface for approximately one hour. During this time, a nano-technology coating is bonded to the footwear sole that increases the traction properties of the surfaces. Once applied to the footwear, the coating causes the surface of the footwear sole to repel debris. This imparts continued tackiness over extended use, from 1 month to up to 3 months depending on amount of use and friction the surface experiences.

A composition for increasing adhesion between two surfaces that are in traction, sliding or rolling-sliding contact with each other is provided. The composition comprises one or more than one first component, where each of the one or more than one first component has a Mohs hardness value of equal to or greater than 7, and one or more than one organic rheology additive. The one or more than one first component and the one or more than one organic rheology additive are present in a ratio from about 90:10 to about 99.9:0.1 (wt/wt). The composition does not comprise water. A method of increase adhesion between two steel surfaces in sliding-rolling contact is also described. The method involves applying the composition to the rail surface at a rate sufficient to increase the adhesion between the two steel surfaces.

A wear and friction article, including on at least one of the surfaces thereof a polymeric material comprising: 20 to 100% by weight of at least one polyetherketoneketone (PEKK); 0 to 80% by weight of one or more fillers; and 0 to 20% by weight of one or more additives. Also, the use of such a polymeric material for reducing wear and/or friction at elevated temperature.

Provided is a friction material composition including: a binder; an organic filler; an inorganic filler; and a fiber substrate, in which a content of copper as an element is 0.5% by mass or less, the friction material composition contains at least one of phlogopite or biotite in a total of from 3% by mass to 9% by mass, and a graphite in an amount of from 2% by mass to 6% by mass, as the inorganic fillers, the at least one of phlogopite or biotite has an average particle size of from 340 m to 1,500 m, and the graphite has an average particle size of from 450 m to 1,100 m.

According to the invention, a melting and traction matrix for use on icy or wet surfaces comprising at least one melting agent and at least one substrate impregnated therewith and a method for making and using same are disclosed. The matrix is applied to surfaces where ice is present or anticipated. Upon surface contact, the substrate provides immediate traction and melting agent dissipates from the substrate. Further melting agent dissipates slowly by diffusion for a long-term, persistent effect, in combination with the substrate, the overall amount of melting agent may be controlled, thereby mitigating potential corrosive, toxic and adverse cosmetic and/or environmental effects. The remaining substrate after melting agent has totally diffused may provide longer traction benefit or may be swept away.
