Abstract: A substrate is provided with a resistant coating by the chemical-vapor deposition of hard material, by passing a gaseous mixture of a precursor of the material, an accelerant, an oxidant, and a carrier gas over the substrate surface, and then removing the by-products and unreacted materials; mixtures of hard materials are obtained by using a co-reagent in the gaseous mixture. The substrate is preferably heated. The figure shows a schematic of the apparatus which includes the precursor (102), the accelerant (104) which are vaporized and transferred to a reactor (120). A mixture of chromium oxide and tin oxide is the preferred coating material, obtained by decomposition of chromyl chloride and monobutyltintrichloride on the substrate surface in the presence of methylisobutylketone and air. Other metal mixtures can also be used.

Abstract: The present invention comprises a polystannoxane catalyst, a curable composition containing the catalyst and a method of using the catalyst and curing the composition.
The curable composition comprises:
(i) a blocked isocyanate;
(ii) a functional component containing reactive hydrogen;
(iii) a polystannoxane catalyst for promoting the reaction of the blocked isocyanate with the functional component.
A co-catalyst may also be employed based on Cu, Zn, Ni, Zr, Ce, Fe, Co, V, Sb and Bi and especially oxides, salts or chelates of said metals. The invention also relates to a method for curing a blocked isocyanate at a low reaction temperature which comprises combining the catalyst with the blocked isocyanate and functional component and heating to a temperature less than about 180°C to obtain a cured urethane.Abstract translation: 本发明包括聚锡氧烷催化剂，含有催化剂的可固化组合物和使用该催化剂并固化该组合物的方法。 可固化组合物包含：（i）封端异氰酸酯; （ii）含有反应性氢的功能组分; （iii）用于促进封端异氰酸酯与官能组分反应的聚锡氧烷催化剂。 还可以使用基于Cu，Zn，Ni，Zr，Ce，Fe，Co，V，Sb和Bi，特别是所述金属的氧化物，盐或螯合物的助催化剂。 本发明还涉及一种在低反应温度下固化封端异氰酸酯的方法，该方法包括将催化剂与封端的异氰酸酯和官能组分组合并加热至低于约180℃的温度以获得固化的聚氨酯。

Abstract: The inventors disclose a process for reducing high current density edge buildup dendrite formation, edge burn, controlling high current density roughness, grain size, and orientation of a zinc coating obtained from an aqueous zinc acidic electrogalvanic coating bath comprising passing a high density current from a zinc anode in the bath to a metal cathode in the bath for a period of time sufficient to deposit a zinc coating on the cathode. The bath contains greater than about 5g/l of a water soluble zinc organosulfonate. A random or block polyoxyalkylene glycol homopolymer or copolymer based on 2 to about 4 carbon atom alkylene oxides. The inventors employ current densities from about 250 to about 4,000 ASF, and optionally, a sulfonated condensation product of naphthalene and formaldehyde, a boron oxide compound, and a lignin compound. The invention also comprises bath compositions.

Abstract: Active Rhodium catalyst and impurities are separated from a hydroformylation process stream containing both active and inactive organo-rhodium catalyst by binding active catalyst and impurities to an acidic ion exchange resin containing an acidic group. The purified hydroformylation stream can be returned to the hydroformylation reactor. All or a portion of inactive rhodium can be reactivated before recycling purified hydroformylation process stream to the reactor. During regeneration of the resin, a neutral solvent is used first to remove impurities which are discarded, then an acidic solvent is used to remove active organic rhodium catalyst from the resin. Such active catalyst can be rehydrided and returned to the hydroformylation reactor. An ion exchange resin having at least one acid group disposed on a silica backbone and an active organo-rhodium complex from a hydroformylation process stream bound to the resin can be produced.
