A wax composition has water repellent and adhesive properties, is cheap and has wide application in the manufacture and treatment of corrugated paperboard, fibreboard, particle board and other cellulosic materials. The liquid composition comprises 1-50 wt % of a wax, 1-30 wt % of a starch and 1-50 wt % of a formaldehyde based resin.

A wax cylinder for a wax spraying machine is disclosed. The wax cylinder includes a housing, an ejection cylinder having a chamber mounted in the housing. An elongated piston is slidably mounted in the chamber and includes a pressure face for pressurizing and urging wax in the chamber out through an ejection opening. The chamber is maintained in constant fluid communication with a feed line for feeding wax into the chamber throughout the stroke of the piston. A check valve is utilized to prevent...

A method of making wax articles and lubricity to textile yarns in which paraffin wax having a particular melting temperature is heated to a temperature above the melting temperature and thereby melted. A mold is then filled with a molten wax while being chilled to a temperature. Thereafter, the mould and the wax in the mould are heated to a temperature substantially the same as the melting temperature and the wax is subsequently removed from the mould. The sequenced chilling and heating impart t...

A wax emulsion is provided which comprises as essential ingredients (A) 100 parts by weight of a petroleum fraction wax having a melting point ranging within 40.degree. to 90.degree. C.; and (B) 3 to 20 parts by weight of an oxygen containing wax; said oxygen-containing wax being prepared by mixing 10 to 80 parts by weight of a petroleum fraction wax (I) having a melting point ranging within 50.degree. to 85.degree. C. with 90 to 20 parts by weight of a polyolefin wax (II) having a melting point...

A process for the preparation of toner comprising (i) aggregating a colorant dispersion with an encapsulated wax; (ii) coalescing or fusing the aggregates generated; and optionally (iii) isolating, washing, and drying the toner.

A wax or wax appearing plastic shade or shell impregnated with a scent material positioned over a heat generating light source. Heat from the light source releases scent material from the material of the shade to derive a desired scent fragrance as the shade is used with the internal light turned on.

A wax composition which can be used as a protective coating, a release agent, or the like, and applied to articles by spraying or brushing the composition onto the article or by dipping the article in the composition or the like. The wax composition comprises a homogeneous combination of a wax and a thermoplastic resin and/or a fatty amide in solution. The solution in a specific embodiment contains a wax, a thermoplastic resin, a fatty amide, an aromatic solvent, an aliphatic petroleum solvent, ...

An improved pattern material for the production of precision investment casting molds, the pattern material being characterized by a low injection temperature, a low coefficient of expansion and insubstantial cavitation after injection into a pattern die. The pattern comprises a mixture in which the predominating constituent is a mixture of stearic and palmitic acids, a thermoplastic resin which is compatible with the fatty acid-wax mixture employed in an amount less than the aforementioned mixt...

Aqueous wax emulsions containing a minor amount of a copolymer of ethylene and acrylic acid, a minor amount of an emulsifier, and water in an amount sufficient to form the emulsion.

A wax burner comprising an upwardly opening wax carrying vessel, a mass of normally solid flammable wax in the vessel, a heat conducting metal heat sink unit within the vessel and in the wax, an elongate, vertical, heat conducting wick structure engaged with the heat sink unit and projecting upwardly therefrom, said wick structure having a heat conducting metal core to conduct heat into said unit, a fibrous sleeve about the core with an exposed flame supporting upper portion and a lower portion ...
