Definitions
- the present invention relates to a primer composition that dispenses with the use of toxic heavy metals and also has a larger edition window for a functioning in the composite adhesion. Furthermore, the present invention relates to a composite material comprising an adhesion promoter layer based on the adhesion promoter composition according to the invention. Another aspect of the present invention relates to a process for producing the composite material and the use of the composite material.
- composite materials are increasingly being used to reduce the empty weight of the bodies.
- Such composite materials are sandwich structures, in addition to metallic components, such as galvanized thin sheets, and organic materials, such as organic polymers containing. These materials combine the high strength of the steel with the low weight of the plastic used.
- the lifetime of the composite of these sandwich structures is determined by the boundary layer between the metal oxide and the polymer used. For a large-scale use of these materials, a stable and permanent adhesion between the different materials must be formed. To ensure this, so-called adhesion promoters or primers are used.
- adhesion promoters are typically aqueous conversion solutions which can be applied to metallic substrates by various methods. These systems are characterized in particular by the fact that they are mostly acidic aqueous solutions that dissolve the metallic base substrate. This metal dissolution leads to a near-surface increase in the pH and subsequent precipitation of inorganic reaction products, which are responsible for the advantageous properties of these coatings.
- the object of the invention is therefore to provide an improved adhesion promoter composition, in particular to provide a primer composition which, without the use of toxic heavy metals, offers a large exposure window for a bond which functions in combination.
