Avoiding errors – ensuring quality

The most common sources of error in chrome plating

When chrome plating with our chrome spray system, cleanliness, care and precision are crucial for a perfect finish. Even small sources of error can lead to unsightly results such as discolouration, dull spots or stains. To help you achieve the best results, we have compiled a list of the most common causes of problems – including practical tips on how to avoid them.

1. Use of unsuitable water

Fully desalinated water with a purity value of at least 2 µS/cm (or 1 MΩ·cm) is essential for all work steps.
💡 Tip: Ensure absolute cleanliness when filling and measure the conductivity regularly with a suitable measuring device.
🔴 Consequences of poor water quality: Yellowish or dirty chrome surfaces – especially after applying protective lacquer.

2. Primer not sufficiently dried

A primer that has not completely cured often causes problems after the protective coating has been applied.
The result: the shiny metal layer loses its brilliance and becomes dull.
✅ Solution: Ensure sufficient drying – using heat if necessary – and make sure the viscosity is set correctly.

3. Contamination under the primer coat

Even the smallest impurities on the substrate can significantly interfere with or even prevent metallisation.
This can lead to staining in the chrome film.
🧼 Note: Absolute cleanliness is paramount throughout the entire process!

4. Technical requirements and application

The special silver spray guns are connected to the liquid containers and compressed air via transparent hoses.

Compressor: at least 250 l/min at 4.5 bar
Oil-water separator with activated carbon filter is essential
Both nozzles must spray evenly
🔍 Regular checks: Ensure that both spray solutions are dispensed evenly and clean the nozzles regularly to ensure optimum results.

5. Correct working practices during metallisation

The technique differs from conventional painting!

The air mist must remain activated throughout.
Move the gun evenly and all around the object.
After longer breaks: thoroughly rinse the feed hoses with deionised water.

⚠️ Caution: Hose A will turn black over time – replace it at least every 6 months!

6. Cleaning and storage

Clean container A regularly with diluted nitric acid.
Concentrate storage: can be stored for at least 6 months in a cool place protected from light.
CLC 1 must be stored in a dark place!
Prepared solutions: can be used for a maximum of 24 hours.
