Typical faults with the spray gun: coating comes away in the area of the air nozzle thread
Why does the coating come off around the air cap thread of my spray gun?
A coating coming away in the area of the air cap thread can be caused by incorrect cleaning and unsuitable cleaning agents. A neutral, aqueous cleaning agent and careful drying will help to avoid damage.
What measures can be taken to prevent damage to the coating?
- Use a neutral, aqueous cleaner: Be sure to check the pH of the cleaner to avoid damaging the coating.
- After cleaning, carefully blow dry: After cleaning, blow dry the spray gun in a disassembled state to remove any residue.
- Important note: Never soak the spray gun in solvent and always clean it in the correct position according to the SATA cleaning instructions.
What causes damage to the coating in the air cap thread?
- pH value of the cleaning agent: If the pH value is below 6 or above 8, the acidic or alkaline solution can attack the coating.
- Insufficient drying after cleaning: If the spray gun is dried in an assembled state, cleaning residues may remain and damage the coating in the thread area.
