摘要： In manufacturing molded product of urethane foam, a releasing agent mainly composed of organopolysiloxane is applied on the inner surface of the mold maintained at 60 DEG C. The agent is prepared by dissolving the base composed of organopolysiloxane composition in an organic solvent. The organopolysiloxane composition comprises (a) a first organopolysiloxane of which 0.1 to 5.0% of all organic groups bonded with Si atoms are vinyl groups, and at least 80% of the remaining organic groups are methyl groups, and (b) a second organopolysiloxane containing at least three Si bonded hydrogen atoms in one molecule, wherein the first and second organopolysiloxanes contain Si vinyl groups and SiH groups at a ratio in a range of 1 : 0.5 to 1 : 5, and do not substantially contain unreactive siloxane. The agent is cured by irradiation with ultraviolet rays. Inside the mold is injected a raw liquid of urethane foam of cold cure-type.

摘要： PROBLEM TO BE SOLVED: To perform spray coating at the normal temp., to make the pot life of silicone semi-permanent and to simplify the cleaning of an apparatus by using a gun jetting a silicone compsn. wherein two or more liquids are mixed to be reacted and cured in a liquid droplet state to emit two or more liquids in a mist form to mix them at the emitting tip of the gun to perform coating. SOLUTION: First and second liquids are respectively put in separate tanks 1a, 1b and sent to spray guns 5a, 5b through airless units 2a, 2b and hoses 3, 4 to be emitted to an adherend in a mist form. The atomized both liquids are mixed at emitting tips to coat the adherend. As the spray guns 5a, 5b, it is unnecessary to use special type ones and, if the ventilation of a work room is performed, an air gun may be used and the number of air guns corresponds to the number of raw solns. to be used. The emitting state and emitting tips of the spray guns 5a, 5b are adjusted so as to be turned to the same space and the surface of the same article to be coated.

摘要： PURPOSE:To produce a urethane foam molded product prevented from the adhesion of a release agent to the surface thereof by uniformly applying the release agent enhanced in release effect to the inner surface of a mold. CONSTITUTION:The inner surface of a mold is coated with a release agent based on organopolysiloxane. An organopolysiloxane compsn. is a mixture of first organopolysiloxane wherein 0.1-5.0% of a total org. group bonded to an Si-atom is a vinyl group and at least 80% of the remaining org. group is a methyl group and second organopolysiloxane containing at least three Si- bonded hydrogen atoms per one molecule and the ratio of the Si vinyl group and the SiN group is within the range of (1:0.5)-(1:5) and both organopolysiloxanes substantially contain no non-reactive siloxane. Further, a platinum compound is added as the reaction catalyst of the Si vinyl group and the SiH group. This release agent is cured by the irradiation with ultraviolet rays or heating to form a thin uniform film on the inner surface of a mold.

摘要： Proposed is an improved aqueous silicone emulsion composition for surface-release treatment comprising a vinyl-containing organopolysiloxane and an organohydrogenpolysiloxane emulsified is an aqueous medium with addition of a platinum compound as a catalyst for the hydrosilation reaction between the silicon-bonded vinyl groups and silicon-bonded hydrogen atoms. Different from conventional silicone emulsion compositions of this type having a pH value of around neutrality, the inventive silicone emulsion composition has a pH value not higher than 5 so that a quite unexpected advantage can be obtained that the stability of the emulsion composition in the curability and other properties after a long period of storage and against mechanical working can be greatly improved.
