# Penetrant Spray \u2013 3 Piece Kit (Part No: 311053)<\/p>\n
This professional, three-piece crack detector spray set is an essential tool for detecting damage to the internal microstructure of aluminum structures, especially hairline cracks. The set is an ideal choice for a comprehensive inspection of body components, such as MacPherson strut towers, particularly when assessing damage after an accident. The method is extremely sensitive, allowing even the smallest defects to be identified while being gentle on the inspected surfaces.<\/p>\n
## Product Description and Operating Principle<\/p>\n
The basis of crack testing is the utilization of the capillary principle. The penetrant (diffusing red dye) found in the set, when applied to the surface, penetrates the finest cracks and pores. After cleaning the surface, the applied white developer attracts the penetrated dye, which, against the white background, reveals the hidden defects by forming an extremely contrasting pattern.<\/p>\n
**Main Advantages:**<\/p>\n
* **High Sensitivity:** Thanks to the high-contrast system, even microscopic cracks are easily detectable.
\n* **Material Compatibility:** The agents do not have a negative effect on welds or treated surfaces.
\n* **Residue-Free Cleaning:** The test agents can be easily removed from the surface with the test agent cleaner without leaving any residue behind.
\n* **Application Area:** Ideally suited for inspecting large surfaces, especially during damage inspection of aluminum body parts.<\/p>\n
## Kit Contents and Application Guide<\/p>\n
The 3-piece set contains all the necessary chemical agents for the test in optimal sequence.<\/p>\n
### Kit Components (Part Numbers and Descriptions)<\/p>\n
| Component | Part Number | Description |
\n| :— | :— | :— |
\n| Crack Inspection Paint (Penetrant) | 311050 | **Ardrox 9VF2 Fluorescent Red:** Capillary action paint that penetrates into the cracks. |
\n| Test Agent Cleaner | 311051 | **Ardrox 9PR5 Cleaner:** Used to remove excess penetrant and contaminants. |
\n| Developer Spray (Developer) | Not specified (part of the kit) | **Ardrox 9D1B:** White aerosol material that highlights the paint within the cracks. |<\/p>\n
*Note: Based on the description, the kit includes products 311050 (Red Penetrant) and 311051 (Cleaner), as well as a developer spray (likely Ardrox 9D1B), although its part number is not listed separately in the main product description.*<\/p>\n
### Detailed Application Process<\/p>\n
To ensure maximum accuracy, the following steps must be strictly followed:<\/p>\n
1. **Surface Preparation:** Thoroughly clean the surface to be inspected with the **Ardrox 9PR5 Cleaner (311051)**. This ensures the surface is free from grease, oil, and contaminants.
\n2. **Penetration:** Apply the **Ardrox 9VF2 Fluorescent Red Paint (311050)** to the area under inspection. Allow it to act for **10-20 minutes**. This time is necessary for the penetrant to enter even the smallest cracks with the help of capillary forces.
\n3. **Cleaning:** After the soaking time has elapsed, thoroughly clean the surface again with the **Ardrox 9PR5 Cleaner**. It is important that no excess penetrant remains on the surface, only what is inside the cracks.
\n4. **Development:** Apply the **developer spray (Ardrox 9D1B)** until an even white layer is formed. The developer reacts with the paint residing in the cracks.
\n5. **Inspection:** Examine the surface. Red lines or dots appearing on the white background indicate structural defects or cracks.<\/p>\n
## Related Accessories and Temperature Monitoring Devices<\/p>\n
Wielander + Schill offers a range of accessories that can assist in body repair and heat treatment processes, especially when machining aluminum parts.<\/p>\n
### Temperature Indicators<\/p>\n
These devices are essential for monitoring heat treatment processes (e.g., welding, heating) to ensure that critical temperature thresholds are not exceeded, which could lead to damage to the aluminum structure.<\/p>\n
#### Temperature Indicator Strip (6 points, max. 160\u00b0C)
\n* **Part No:** 311060
\n* **Features:** Cost-effective solution for mass application, space-saving design. Indicates irreversible temperature overshoot. Features a horizontal, six-point scale in degrees Celsius (\u00b0C).
\n* **Application:** Temperature monitoring during the heating of aluminum components, for example, before shrinking or straightening operations.
\n* **Packaging:** 1 x 10 flat sheet.<\/p>\n
#### Temperature Indicator Strip (6 points, max. 127\u00b0C)
\n* **Part Number:** 311061
\n* **Features:** Similar to the 160\u00b0C version, this pencil indicates the 127\u00b0C temperature limit. Ideal for lower temperature processes.
\n* **Packaging:** 1 x 10 flat sheet.<\/p>\n
#### Temperature Indicator Pencils (With Calibrated Melting Point)<\/p>\n
These temperature indicating pencils feature a calibrated melting point. When the indicated surface temperature reaches the nominal value of the pencil, the mark melts (runs off), providing a clear visual indication. Accuracy: +\/- 1% compared to the nominal temperature.<\/p>\n
**Applications:** Welding and metalworking, preheating, intermediate holding, post-weld heat treatment, softening, stress-relieving welds.<\/p>\n
| Product | Part Number | Nominal Temperature | Color |
\n| :— | :— | :— | :— |
\n| Temperature Indicating Pencil | 311062 | 100 °C | Red |
\n| Temperature Indicating Pencil | 311063 | 204 °C | Green |
\n| Temperature Indicating Pencil | 311064 | 400 °C | Yellow |
\n| Temperature Indicator Pencil | 311065 | 500 \u00b0C | Blue |<\/p>\n
**Method of Application:** Mark the workpiece before or during heating. The melting (flowing away) of the mark clearly indicates that the temperature has been reached. This method is best suited for smooth surfaces.<\/p>\n
