Part number: 341003
The Wieländer+Schill Flame Coating Set is a special surface treatment tool that performs surface silicification (silicate formation) based on the principle of flame pyrolysis. This professional set is an essential preparatory step for the riveting and bonding processes of aluminum surfaces, as it prevents direct oxidation of the metal, thereby drastically improving adhesion.
The flame coating set works by using a special gas mixture (propane, butane, and PYROSIL – a substance containing organic silicon compounds). During the process, the organic silicon compounds decompose in the flame, forming an extremely thin, nanoscale, yet very dense and firmly adhering $text{SiO}_2$ (silicon dioxide) layer on the treated surfaces.
This nanothick layer (5–100 nm) significantly improves adhesion, whether for paint, coating, or adhesives. The technology is ideal for preparing small and medium-sized aluminum surfaces before riveting and bonding. The resulting amorphous silicon dioxide layer adheres excellently to metals, glass, ceramics, and plastics alike.
PYROSIL® precursors are silicon-containing substances that are fed into the natural gas or propane flame during the PYROSIL® treatment (silicification).
The 7-piece flame coating set contains the following components that ensure comprehensive and effective surface treatment:
| Item | Part number | Quantity | Description |
|---|---|---|---|
| Burner | N/A | 1 stück | The device for flame generation and PYROSIL® dosing. |
| Burner stand | N/A | 1 stück | Used for safely positioning the burner. |
| Pyrosil adhesion promoter (Primer) | 347004 | 2 pcs | SURALink 021 (GP15), 50 ml packaging. |
| Pyrosil Refill MGK | 347005 | 2 pcs | Fuel gas mixture (propane/butane + PYROSIL®). |
| Spatula | N/A | 2 pcs | An auxiliary tool for handling the materials. |
| Total | 7 pcs |
This PYROSIL®-based primer (SURALink 021, GP15) functions as a base coat and activator for two-component automotive body adhesives. It significantly enhances the adhesion of metal coatings on the treated surface.
Application: Primer and activator for 2K automotive adhesives.
Effect: Significantly improves the adhesion of metal coatings.
Drying time: Approximately 20 seconds at room temperature.
The MGK is a fuel gas mixture consisting of propane and butane, supplemented with PYROSIL® (organic silicon compounds). This material burns in the burner flame, ensuring the formation of the $text{SiO}_2$ layer.
Function: Material for the ignition kit, for starting and sustaining the combustion process.
Chemical composition: Propane and butane gas mixture, enriched with PYROSIL®.
Result: Formation of a dense, strongly adhering $text{SiO}_2$ layer during combustion.
The use of the flame coating kit brings numerous advantages in the field of body repair and industrial surface treatment:
Excellent Adhesion: The resulting nanothick layer of silicon dioxide dramatically increases the adhesion capacity of surfaces, which is critically important for the durability of bonding and riveting processes.
Oxidation Prevention: Immediately after treatment, it prevents the re-oxidation of aluminum surfaces, which is particularly important for workpieces exposed to air.
Material Compatibility: Suitable for surface treatment of metals, glass, ceramics, and plastics.
Fast Processing: The drying time of the primer (347004) is extremely short (approx. 20 sec), which speeds up the workflow.
Professional Quality: The flame pyrolysis technology guarantees an extremely dense and homogeneous coating.
This kit primarily provides indispensable assistance in the following areas:
Body Repair: Before bonding and riveting aluminum components to maximize joint strength.
Paint preparation: Preparation of any surface (metal, plastic) before applying paint or coating for better adhesion.
Handling of special materials: Activation of ceramic and glass surfaces for special binders.
