Abstract: Surfactants made by the successive ethoxylation and propoxylation of diamines are effective in providing a fine-grain tin coating in high-speed strip-steel plating operations under conditions of high current density. Surfactants prepared by successive propoxylation and ethoxylation are also effective.

Abstract: A process and apparatus for regenerating a plating bath comprising trivalent chromium cations (a trivalent chromium bath). The bath can be continuously, or more preferably, periodically with an ion exchange resin, preferably a cation exchange resin. A useful apparatus comprises a plating tank containing a trivalent chromium plating bath in communication with an ion exchange bed continuing ion exchange resin.

Abstract: A sulfate scavenger for chromium-plating baths consists of barium chromate or dichromate or mixtures of the two, added either directly to the bath or as part of a replenishment mixture with chromic acid.

Abstract: The present invention provides a process for electroplating chromium using lead anodes while achieving the advantages of using methanesolfonic acid without suffering the excessive anode-corrosion characteristics associated with that acid. Accordingly, chromium is electrodeposited from a bath containing chromic acid, sulfate and an alkylpolysulfonic acid containing from one to about three carbon atoms. The invention also provides a plating process for chromium electrodeposition, a plating bath for use in the inventive process, and a replenishment composition for existing plating baths.

Abstract: An improvement in the preparation of printed circuits comprises inserting a deformable layer between the phototool or support layer, and the solder mask. The deformable layer provides a uniform, integral and relatively thin coating of solder mask over circuit components, and results in higher-quality solder joints and lower rejection rates for finished boards.

Abstract: A hood for coating glass articles has side walls and a top part, forming a tunnel through which hot glass articles pass; blowing and suction channels in the active part of the hood are formed to present substantial line contacts facing the ware being coated. By introducing relatively large radiating surfaces, the buildup of reaction-product crust on the interior of the apparatus is minimized.

Abstract: Apparatus for the coating of glass containers has a series of vertical slots for applying coating chemicals to a hot glass jar with a minimal neck and shoulder area. An opposing horizontal slot exhausts spent coating material and reactants in a laminar flow. A center section provides a current of gas without chemicals parallel to the coating stream, and flowing with low velocity relative to the coating stream, but with high velocity relative to the extraneous turbulent and convection currents.

Abstract: A coating applicator is provided for depositing a film on a surface of glass or other substrates by chemical-vapor deposition. The applicator includes a pair of opposing coating nozzles for applying a vaporized coating-chemical reactant in a carrier gas to the surface at such a concentration and velocity that coating of the surface is achieved under substantially reaction-rate-controlled conditions. Each coating nozzle is positioned adjacent the surface with a small clearance therebetween, the clearance being open to the outside atmospehre. The opposing coating nozzles are directed toward each other at a selected angle with respect to the surface of the substrate. The angle and the clearance provide a condition where there is substantially no intermixing of coating vapors with the outside atmosphere.

Abstract: A method for producing coatings on a heated substrate, preferably glass, comprises pretreating the substrate with a gaseous composition of water, air and a fluorine compound, and thereafter depositing a fluorine-doped tin-oxide coating on the substrate.

Abstract: Improved apparatus for coating glass containers provides a coating on the body for improved resistance to impact breakage and abrasion, while coating of threads or lugs at the open tops of the containers is limited to about one-tenth, or less, of the coating on the surfaces of the body, which surfaces are exposed to contact with other containers during handling. The apparatus provides a laminar flow of fluid which is free of coating-precursor chemical over the threads or lugs in a manner which minimizes turbulence and intermixing with the coating stream.

Abstract: An electroplating bath, cell and method for the electrodeposition of a wide range of tin-bismuth alloys onto a conductive substrate comprises tin and bismuth ion in aqueous solution, and an alkyl sulfonic or polysulfonic acid or salt as the electrolyte. The sulfonic component is present in amounts sufficient to maintain the bismuth in solution.In the operation of the method of the invention, electroplated tin-bismuth eutectic alloys of controlled composition are obtained. The alloys of tin and bismuth contain amounts of both metals such that the plated alloy has a melting point substantially lower than that of either metal alone, and a melting point lower than that of a tin-lead alloy.

Abstract: A liquid coating composition comprises an organotin di- or tricarboxylate and an organic fluoroacid for forming a fluorine-doped tin-oxide coating on glass having good bulk resistivity and haze values. The method of coating a transparent substrate with the composition is also described. The preferred liquid coating composition comprises about 50 to 80 wt. % of dibutyltin diacetate, and about 20 to 50 wt. % of trifluoroacetic acid.
