摘要： The present invention relates to a mixture of polyalkylsiloxanes obtainable through a hydrosilylation reaction wherein a mixture of monounsaturated olefins is reacted with an amount of one or more polyalkylhydrosiloxanes in the presence of a hydrosilylation catalyst. Furthermore, the invention concerns polyalkylsiloxane comprising alkyl side chains consisting of linear or branched alkyl groups with 40 to 60 carbon atoms, with 16 to 30 carbon atoms, and 6 to 15 carbon atoms. In addition, the present invention relates to water-based compositions suitable for use in metal casting processes as a mold release agent comprising a mixture of polyalkylsiloxanes, a non-ionic surfactant having a HLB value of at least 8, and less than 20 wt.-% of waxes. In addition, the present invention relates to the use of the polyalkylsiloxanes and mixtures of polyalkylsiloxanes.

摘要： A core forming method is provided for forming a core. The core forming method includes forming one or more mold parts of water-soluble polymer (WSP), each mold part including a bond area and a part forming area, moistening the bond areas, bonding the mold parts together with the bond areas moistened and the part forming areas aligned to form a cavity shaped as a negative of the core, injecting a slurry, which is non-reactive with the WSP, into the cavity and removing the WSP with water once the slurry is cured.

摘要： A composition which comprises a soluble or partially soluble phosphate, a refractory material and less than 1% of an oxide or hydroxide of magnesium or calcium. The composition may be mixed with water to form an investment casting slurry into which a wax pattern may be dipped. Slurry coated onto the pattern may be set by applying a stucco composition which comprises an oxide or hydroxide of magnesium or calcium. Coats of set slurry may be built up on the pattern to form an investment casting shell.

摘要： A molding material mixture contains cellulose nanofibers (CNFs) and at least one base material selected from the group consisting of a resin and fibers. A hydrophobic polymer is chemically bonded to at least some of the —OH groups of the cellulose nanofibers. The base material and the cellulose nanofibers are ground or pelletized. A method for producing the molding material mixture includes the following: a pre-irradiation step of applying an aqueous dispersion of CNFs to a base material sheet or immersing a base material sheet in the CNF aqueous dispersion, irradiating the base material sheet with an electron beam, and bringing the base material sheet into contact with an aqueous solution or an aqueous dispersion containing a hydrophobic monomer so that the hydrophobic monomer is graft-polymerized onto the CNFs, or a simultaneous irradiation step of mixing an aqueous dispersion of CNFs with a hydrophobic monomer to form a solution, applying the mixed solution to a base material sheet or immersing a base material sheet in the mixed solution, and irradiating the base material sheet with an electron beam so that the hydrophobic monomer is graft-polymerized onto the CNFs; a drying step; and a grinding or pelletizing step. The present invention provides a molding material mixture that contains cellulose nanofibers and at least one base material selected from the group consisting of a resin and fibers, and that can be handled as a ground product or pellets, and also provides a method for producing the molding material mixture.

摘要： A release agent for separation of a pattern from a mold cavity or core or the like. The agent consists essentially of an organosiloxane polymer fluid, comminuted aluminum, and a fluorocarbon solvent. Illustratively, the agent may include 0.6% by weight of the organosiloxane polymer fluid. The illustrative organosiloxane polymer has a viscosity of approximately 12,500 centistokes. The illustrative agent includes 3.6% by weight of an aluminum paste including approximately 65-75%, by weight, of finely divided pigment-grade aluminum and 25-35% of mineral spirits vehicle. The fluorocarbon preferably is a non-propellant grade fluorocarbon such as trichlorotrifluoroethane.
