摘要:
The reactive injection molding of a urethane-based resin composition according to the invention is performed by admixing the polyol compound as one of the reactants of the urethane-based resin with a specific organopolysiloxane as an internal mold release agent so that the molding process can be performed without application of an external mold release agent to the metal mold. The organopolysiloxane is characterized by two types of substituent groups bonded to the silicon atoms, of which the first type is --C.sub.x H.sub.2x OR', R' being a monovalent hydrocarbon group of 8 to 30 carbon atoms free from chain end unsaturation and x being 0-4, and the second type is --C.sub.y H.sub.2y (OC.sub.n H.sub.2n).sub.m OH, y being 1-4, n being 2-4 and m being 0-45.

摘要:
Use of an ink composition containing an organopolysiloxane having at least one hydrophilic group can bring about such a lithographic printing using a dampening solution as the non-image area is hardly stained, the image area is given a sufficient density, emulsification hardly occurs and tolerance for change of printing conditions is high.
摘要:
The invention provides an organopolysiloxane having at least one polyhydric pendant group bonded to the silicon atom as derived from a polyglycerol compound. Such an organopolysiloxane is useful as a non-ionic surface active agent. The organopolysiloxane can be prepared by the hydrosilation reaction between an organohydrogenpolysiloxane having at least one hydrogen atom directly bonded to the silicon atom and a polyglycerol compound having an aliphatically unsaturated linkage in the molecule such as those obtained by the reaction of allyl alcohol and glycidol or by the reaction of diglycerin and allyl glycidyl ether.
摘要:
A nail enamel composition prepared by dissolving a solid resin and an organopolysiloxane, particularly a copolymer having a polysiloxane structure and a polyoxyalkylene structure, together in an organic solvent. The composition forms a film on the surface of the finger-nail and the film thus formed can easily be peeled off.
摘要:
A silicone grease composition comprising 3-30 wt % of an organopolysiloxane and 60-96.9 wt % of a heat conductive filler is diluted with a least volatile isoparaffin having a boiling point of 260-360° C. Despite a heavy loading of heat conductive filler, the grease composition is easily applicable to heat sinks as a thin uniform coating. The composition is drastically increased in shelf stability at room temperature, easy to handle, and provides for good heat dissipation.

摘要:
Disclosed is a water repellent for fibers, comprising an acryl-silicone graft copolymer which is prepared by a radical copolymerization reaction of an organopolysiloxane compound containing one radical polymerizable group with radical polymerizable monomers including an acrylate, a methacrylate or a mixture thereof as a main member.
摘要:
Organopolysiloxane powder is prepared from an organopolysiloxane solution by admitting the organopolysiloxane solution into a planetary-screw mixer and agitating the solution at a sufficient temperature to allow a low-boiling liquid component to evaporate from the solution, thereby separating the low-boiling liquid component from the solution.
