Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying corrosion protection layers to metal surfaces, particularly edges and transitions, are inefficient and often result in uneven applications, failing to ensure complete protection against corrosion.
Innovation Solution
The use of an adhesive tape with a meltable special polyolefinic layer, which is heated to form a smooth, uniform corrosion protection layer on metal surfaces, providing excellent adhesive properties and ease of application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pumpable PVC plastisol is sprayed locally onto the metal surface and smoothed over using a brush, then the fine seam can be applied to edges and transitions, but the surface remains rough and uneven application is visible
Solution Approach 1:
The patent changes the physical state of the corrosion protection material from a pumpable paste (plastisol) to a meltable solid (polyolefinic layer). This parameter change allows the material to be applied as a solid tape that melts and flows smoothly upon heating, eliminating the rough surface and uneven application problems associated with brush-smoothed plastisol while maintaining ease of local application to edges and transitions
2Reliability
If a corrosion protection layer is applied to the entire surface of metal components, then complete protection is achieved, but the process is complex and time-consuming for small areas like edges and transitions
Solution Approach 1:
The patent applies the corrosion protection layer locally to specific areas (edges and transitions) using a tape that can be precisely positioned and applied only where needed. The meltable polyolefinic layer ensures complete coverage of these small areas when heated, providing reliable corrosion protection without the complexity and time consumption of treating entire surfaces
3Ease of operation
If manual or robotic fine seam sealing is used, then edges and transitions can be protected, but the application is difficult to control for optimal optical quality
Solution Approach 1:
The patent employs a self-adhesive tape with a meltable polyolefinic layer that automatically conforms to the metal surface geometry when heated. The material self-levels and flows into joints without requiring manual or robotic manipulation, providing both application flexibility and consistent optical quality through the inherent self-adjusting properties of the melting material

Function Achieved in This Case
This method simplifies the corrosion protection process, ensuring complete coverage and durability on small areas like edges and transitions, maintaining a smooth surface and resisting thermal changes and mechanical stress.
Implementation Method 1
The layer is a material of this type which melts when heated, spreads over the metal surface when heated, can flow into joints and thereby forms a closed and smooth corrosion protection layer
Implementation Method 2
the adhesive tape is applied to the respective metal surface and then heated. The layer is a material of this type which melts when heated, spreads over the metal surface when heated

AI summary
The invention relates to a method for corrosion protection treatment of metal surfaces, particularly edges and transitions of metal components, characterized in that an adhesive strip with a layer of an olefin polymer having a density between 0.86 and 0.91 g/cm3 and a crystallite melting point of at least 105° C is applied onto the metal surface and the strip is heated such that the layer is molten, thereby forming a corrosion protection layer.
