Abstract: A substrate onto which a coating solution is dropped is rotated at a low speed in a first rotational mode and then after an interval of time at a high speed in a second rotational mode. At the end of the first rotational mode, the coating solution is coated to a thickness larger than a given thickness on irregularities on the substrate such as twin patterns and a global pattern, with the coating solution being coated to a thickness smaller than the given thickness between the twin patterns. Subsequently, at the start of the second rotational mode, the coating solution coated on the twin patterns and the global pattern flows into spaces between these patterns. At the end of the second rotational mode, the thickness of the coating solution on the twin patterns is almost nil, and the thickness of the coating solution on the global pattern is small in its entirety though it is somewhat large in the central area of the global pattern.

Abstract: An organopolysiloxane composition comprising (A) 80-95 parts by weight of a silicone resin comprising units of R3SiO1/2 and SiO4/2 in a molar ratio of from 0.6/1 to 1.1/1, wherein R typically represents methyl, (B) 5-20 parts by weight of a diorganopolysiloxane, and (C) from more than 40 to 500 parts by weight of an organic solvent is applied to various substrates and fired into a ceramic film having improved heat resistance and adhesion.

Abstract: The present invention relates to a process of preparing emulsions of hydrolyzable silanes, such as alkoxysilanes, using an oil concentrate. The emulsifiers are initially stirred with water. An oil concentrate is then prepared by adding a hydrolyzable silane to the stirring mixture of emulsifiers and water. Additional water is then dispersed in the oil concentrate to form the desired emulsion. Emulsions prepared by this process have shelf stability that is 6 months or longer.

Abstract: A novel perfluoropolyether-modified aminosilane cures into a film having improved water and oil repellency, parting and anti-staining properties. A surface treating agent comprising the aminosilane, and an article with a coating of the aminosilane are also provided.

Abstract: A curable resin composition containing (A) a saturated hydrocarbon polymer having at least one reactive silicon-containing group in a molecule, and (B) a hydrogenated oligomer of an &agr;-olefin, or a curable resin composition containing (A) a saturated hydrocarbon polymer having at least one reactive silicon-containing group in a molecule, (C) a saturated hydrocarbon oligomer, and (D) an ester plasticizer, both of which have good workability, in particular, at low temperature.

Abstract: A condensation curable coating composition comprises the following and any reaction product thereof: (A) a room temperature vulcanizable polyorganosiloxane composition; and (B) a marine foul release-enhancing proportion of at least one organic compatible silicone fluid free from silanol groups and being capable of blooming to the surface of a cured product of component A.

Abstract: An air sprayable, fluid, non-metallic coating mixture to provide an article coating having the ability to reflect at least 75% of heat energy in the frequency range of up to 2.6 microns comprises the combination of two different alpha alumina powders. A first powder predominantly is in a particle size range of less than about 1 micron; a second powder is of a particle size greater than 7 times the particle size of the first powder. The mixture includes a glass powder having a melting point of at least about 1400° F. and of a particle size less than about 45 microns. The mixture includes a binder that will form up to about 80% of its weight in silica when heated to a temperature of at least the melting point of the glass powder. In the article coating, provided by air spraying the mixture onto an article and heating to a temperature sufficient to melt the glass powder and to form the silica from the binder, the glass and silica form a matrix about and binding together the alumina powder.
