摘要:
The introduction of a room-temperature-curable organopolysiloxane composition that cures at room temperature to give a rubber whose surface is easily coated with paint and from which the resulting paint film does not delaminate readily and that after curing is free from staining of the surface of the rubber and any substrates in contact with the rubber.
摘要:
A highly storage-stable room-temperature-curable organopolysiloxane composition that cures to yield a product whose surface resists staining and that does not cause staining of the neighboring regions of the substrate in contact with said cured product. The organopolysiloxane composition is made from a polydiorganosiloxane, an imidazolinyl-functional organosiloxane, a filler, and a crosslinking compound which is a Si-bonded hydrolyzable group-containing organosilane or organosiloxane oligomer.
摘要:
A room-temperature-curable composition is very storage stable under seal at room temperature, cures to give a rubbery elastic material with excellent physical properties, and is useful as a sealant composition when polyoxyalkylene has at the terminals groups of the formula ##STR1## of which one example of a organosiloxane-modified polyoxyalkylene is ##STR2## in which Me is methyl.

An apparatus for preparing frozen products having a mix tank, a freezing chamber, a liquid mix supply means, a dispensing device, a freezing means for the freezing chamber comprising independent first and second freezing systems, and a frozen control means comprising a first and second frozen control means for said first and second freezing systems respectively, and making it possible that liquid mix in the freezing chamber may be always frozen in good condition. Further an apparatus for preparing frozen products having a frozen and chilled control means for the freezing means independently, and making it possible that liquid mix is stored in the freezing chamber when the freezing operation does not occur.

At a transmitting end, first and second dipole antennas are crossed each other by right angles and are arranged in a plane perpendicular to a propagating direction of radio wave. In first and second balanced modulators, a carrier signal is modulated with respective modulation signals having a phase difference of 90.degree. to produce balanced-modulated signals, which are then supplied to the first and second dipole antennas, respectively. Then a plane of polarization of a composite vector of radio waves transmitted by the dipole antennas is rotated at a frequency of the modulation signals, said frequency being higher than a fading frequency. The modulation signals are controlled by a state of a digital signal to be transmitted. At a receiving end, the digital signal is reproduced by receiving the transmitted radio wave by a conventional single side band receiver.
摘要:
A method for the preparation of one-package room-temperature-curable silicone compositions that do not slump prior to their cure, do not crack or fissure during their cure even when deformed by an external force, and do not yellow where an example of the room-temperature-curable silicone compositions is (a) hydroxyl-terminated diorganopolysiloxane, (b) oxime-functional organosilicon compound, and (c) inorganic filler according to the following four steps: step (1) in which 20 to 70 weight % of the total amount of component (a) is mixed with methyltris(methyl ethyl ketoximo)silane, step (2) in which component (c) is added and mixed into the mixture prepared in step (1), step (3) in which 30 to 80 weight % of the total amount of component (a) is mixed with vinyltris(methyl ethyl ketoximo)-silane, step (4) in which the mixture prepared in step (3) is mixed with the mixture prepared in step (2).
