| Popis: | Since the introduction of the organosilicon products into industry in 1943, the potentialities of these compounds appear to be unlimited. Their more recent introduction into cutaneous medicine 1 suggests many uses for their water repellent and lubricating properties in general medicine and surgery. The physical and chemical differences of the silicones and organic compounds are marked, because the silicones have a quartz-like skeleton consisting of alternating silicon and oxygen atoms rather than the carbon atom framework of the organic compounds. 2 The silicones are water repellent, superior lubricants, which are chemically and physiologically inert and show marked surface adhesiveness. Physical properties 3 are remarkable in that the freezing point for the 500 centistoke (viscosity) DC 200 fluid is —50 C (—58 F). The boiling point for this fluid is 200 C (392 F), and the viscosity-temperature coefficients (viscosity-temperature coefficient equals 1—viscosity at 210 F / viscosity at 100 F)are in the |
