Abstract: The invention concerns a method which consists in: providing a protective treatment against corrosion to the initial sheet metal using an aqueous emulsion containing colloids based on acrylic and/or methacrylic polymer; a step which consists in applying a coat of liquid enamelling composition comprising an enamel frit capable of being vitrified; a baking step adapted to vitrify said frit. The invention is characterised in that said method does not comprise a step for degreasing said surface subsequent to the protective treatment. The invention provides the advantages of improved adherence of the enamel and a simpler process.

Abstract: A composition and method for treating oversprayed paints in paint spray booths is provided. The composition includes an aqueous solution of a compound such as chitosan, and a complex metal salt, such as aluminum chlorohydrate, capable of flocculating the oversprayed paint, and optionally, bentonite clay. The composition is useful for detackifying and flocculating oversprayed paint, and is particularly useful as a liquid concentrate for the addition to wash systems in paint spray booths for water-based and solvent-based paints. The composition is also useful in decreasing the time for phase separation of the organic phase and the aqueous phase in solvent-based removal processes.

Abstract: A corrosion-resistant coated strap is formed from an elongated metal strap base element having a width and a thickness and defining first and second sides and a pair of edge regions. A coating is applied and cured onto the base element. The coating has a substantially consistent thickness at the first and second sides and at about the edge regions. A method for making the coated strap includes providing a metal strap and conveying the strap through a coating apparatus. A powder is electrostatically applied on the first side of the strap, which covers the first side and the opposing edges. The powder is applied on the second side of the strap, covering the second side and the opposing edges. The powder is melted to form a flowable material and is cured on the strap. The coating method is carried out in an in-line strap manufacturing process.

Abstract: The invention includes a method of coating a substrate, comprising exposing a substrate to an initiator capable of initiating a graft polymerization reaction on the substrate, to generate reactive radical sites on the surface of the substrate; contacting the substrate with a composition comprising one or more monomers in a medium which has different hydrophilicity compared to the substrate, and grafting monomer molecules onto the substrate by forming covalent bonds between monomer molecules and the substrate at reactive radical sites on the substrate surface. With the invention, novel coated articles can be obtained which are particularly useful as medical products such as catheters.

Abstract: The invention is a method for treating a worksurface of a workpiece to render it static dissipative under conditions of low relative humidity. Conditions are created that render the worksurface receptive to treatment with a electrostatic dissipative (ESD) agent. The receptive worksurface is contacted with an ESD agent. Finally, the conditions created to render the worksurface receptive are removed. One method for treating a worksurface of a workpiece to render it static dissipative under conditions of low relative humidity commences by contacting the worksurface with an aqueous bath comprising acid and poly(3,4-ethylene-dioxythiophene)-poly(styrenesulfonate). The worksurface is removed from the bath and excess bath is washed away from the worksurface. The worksurface finally is dried. The preferred acid is HCl. Another method involves heating the worksurface to render it receptive followed by treating with heated worksurface with the ESD agent and subjecting the treated worksurface to pressure.
