Abstract:
The invention relates to a method for permanently joining an essentially flat support material to a substrate, in particular for laminating a plastic film to a metal substrate, wherein the at least essentially flat support material and/or the substrate is/are initially impinged upon by a connecting agent, preferably, an adhesive and subsequently the support material and the substrate are brought together in such a manner that the support material is permanently connected to the substrate, in particular, the plastic film is laminated on the metal substrate, and optionally, measuring and/or shaping of the thus formed composite material is carried out.

Abstract:
A resin-lined steel pipe, characterized in that it has an adhesive layer on the inner surface of the steel pipe and, provided on the inside the adhesive layer, a plastic layer, it exhibits an initial shear adhesion of 2.0 MPa or more between the steel pipe and the plastic layer, and the inner surface of the steel pipe is in advance subjected to an undercoat treatment wherein a chemical treatment film formed by using a phosphate is subjected to a grain fining treatment, and preferably an epoxy primer layer is provided between the steel pipe and the adhesive layer. A method for producing the resin-lined steel pipe which comprises inserting a plastic pipe having an adhesive layer on the outer surface thereof into a steel pipe having been subjected to the above undercoat treatment, the plastic pipe having an outer diameter less than the inner diameter of the steel pipe, narrowing the outer diameter of the steel pipe, to bring the plastic pipe to intimate contact with the steel pipe, and then heating them at a temperature of the temperature for completion of the melting of the adhesive layer or higher and lower than the temperature for the beginning of melting of the plastic pipe.
Abstract:
A composite small-diameter tubing (18) resistant to interaction with materials conveyed therethrough such as liquids containing alcohols or corrosive agents which includes a cylindrical outer metal conduit (12) having a hollow central shaft extending longitudinally therethrough defined by an interior wall; and a continuous non-reactive interior tube (18) surrounded by and positioned within the cylindrical metal conduit. The tubing (18) can be manufactured by a process which includes the steps of a) positioning a length of non-reactive tubing (18) having a predetermined outer diameter within an inner diameter of metal tubing (12) of essentially corresponding length, the metal tube (12) having an unsealed side seam, wherein the inner diameter is greater than the outer diameter of the non-reactive tubing; and b) sealing and reducing the metal tubing (12) to an outer diameter essentially equal to the predetermined outer diameter of the interior tubing (18). The non-reactive interior tube (18) may be made of a suitable polymeric material.

Abstract:
The invention relates to a method for producing a three-dimensional substrate with a protective and decorative layered composite. According to said method, a priming layer which consists of a coating agent (I) and which is electrically conductive when baked is applied to an electrically conductive substrate without spraying and baked. A substrate which is not yet in the desired three-dimensional form is then formed, a second coating layer consisting of a coating agent (II) which can be deposited by electrophoresis is deposited electrophoretically and baked, and a plastic film is applied.
Abstract:
The invention provides a method for improving the adhesiveness between high molecular materials and metallic materials, and for improving the characteristics and long-term stability of composite materials comprising high molecular materials and metallic materials. Prior to bonding the high molecular resin to the metallic material, the metal surface is treated with a sulphur-containing organic compound which contains (A) at least one functional group which is a carboxyl group or a carboxylic acid anhydride group, and (B) at least one functional group which is a mercapto group or a thioether group.
Abstract:
Gegenstand der Erfindung ist ein Verfahren zum dauerhaften Verbinden eines zumindest im wesentlichen flächigen Trägermaterials mit einem Substrat, insbesondere zur Kaschierung einer Kunststoffolie auf ein Metallsubstrat, wobei das zumindest im wesentlichen flächige Trägermaterial und/oder das Substrat zunächst mit einem Verbindungsmittel, vorzugsweise einem Klebstoff, beaufschlagt wird bzw. werden und anschließend das Trägermaterial und das Substrat zusammengebracht werden derart, daß das Trägermaterial dauerhaft mit dem Substrat verbunden wird, insbesondere die Kunststoffolie auf das Metallsubstrat aufkaschiert wird, wobei sich nachfolgend gegebenenfalls eine Dimensionierung und/oder Formgebung des auf diese Weise erzeugten Verbundmaterials anschließen kann.
