❓ Frequently Asked Questions (FAQ)
What water quality is required for rinsing and preparation?
Use demineralized/DI water (<10 µS/cm). Tap water causes salt stains/streaks. Check conductivity regularly and replace resins/filters in a timely manner.
What are the ideal environmental conditions (temperature/humidity)?
18–25 °C, <70 % RH. Low temperatures slow down reactions; high humidity promotes water haze and loss of gloss.
How do I prepare the surface correctly?
Degrease → sand finely → clean dust-free → apply suitable primer and allow to cure completely. Wear gloves/take precautions against static electricity.
What nozzle size and spray pressure are recommended?
Lacquers: 1.2–1.4 mm; thin solutions: 1.0–1.2 mm; pressure 1.8–2.2 bar (at the cap). Refer to the data sheet for exact values and check against a sample part.
What should the layer thicknesses and overlaps be?
Several thin, uniform passes with 60–70% overlap. Metallization chemicals are applied until the mirror image appears homogeneous.
How long are the ventilation and drying times?
Intermediate coat times typically 10–15 min at 20 °C; final curing after 24 h. Optionally accelerate curing: 60 °C / 30 min (if approved).
How long do concentrated solutions and prepared baths last?
Original concentrates have a shelf life of 12–24 months (cool/dry). Use prepared solutions according to the manufacturer's instructions, checking parameters (pH, conductivity, temperature).
Can I combine CLC products with third-party systems?
Only after prior adhesion/compatibility testing. The system-compatible combination (base coat A/B/C, activator, top coat) is recommended.
How do I prevent tarnishing or "yellowing"?
Ensure DI water quality, correct sequence/times, sufficient rinsing, fresh solutions and constant temperature; avoid residues (surfactants).
Clouds/streaks in the reflection – what to do?
Adjust wetting, reduce humidity, check surface, renew baths if necessary. Adjust parameters according to data sheet, improve rinsing quality.
Improve adhesion and scratch resistance?
Allow the system to fully cure, then use the approved topcoat. Sand between coats only according to the work instructions. Forced drying can help.
Is the system VOC-compliant?
Depending on the product. Refer to the technical data sheet for information (e.g., VOC-compliant filler).
What PPE is required?
Protective gloves, safety glasses/visor, long-sleeved clothing; depending on the product, respiratory protection (A2/P3) and extraction system. Observe SDS/CLP.
How do I clean equipment and dispose of leftover quantities?
Use suitable cleaning agents/thinners; collect rinse water/chemical residues separately and dispose of properly. Do not discharge into the sewer system.
How do I mask areas that should not be chrome-plated?
Heat-resistant, chemical-resistant tape/film; rub edges clean. Carefully peel off after the process to avoid edge breakage.
On which substrates does spray chrome plating work?
Plastics (ABS/PC, PP with adhesion promoter), metals, glass, painted surfaces. Adhesion is substrate-dependent – preliminary tests are mandatory.
Is spot repair possible?
Limited: perform local sanding, reactivation/metallization and clear coat bonding; polish transitions cleanly.
Maximum gloss/mirror effect – how?
Perfectly smooth, dust-free base; fully cured primer; fresh, clean baths; controlled environment; orange peel-free topcoat.
Wetting problems – does the chemical bead up and roll off?
Surface hydrophobic/silicone-containing or primer not fully cured. Check pre-cleaning/antistatic properties, optimize activation.
Are there tight process windows/times between steps?
Yes. Activation → Metallization → Rinsing have defined time windows. Exceeding these windows leads to loss of adhesion/gloss. Refer to the data sheet for timing.
How do I document the process?
Record batch IDs, conductivity, pH/temperature, nozzles/spray pressure, paths/times, climate and photos of the reference parts.
Proper storage of chemicals and paints?
Store at 10–25 °C, in a dry, UV-protected location; tightly close containers. Store incompatible materials separately; observe FIFO and expiration dates.
Whitening/milky haze in clear coat – solution?
Mostly high humidity/layer too wet. Warm air/forced drying, longer drying time, suitable dilution, thinner coats.
How to keep the chrome tint/color glaze consistent?
Precise dosing, same nozzle/pressure, identical paths; clear coat layer constant; always compare reference sample with target sample.
Dust inclusions – what to do?
After curing, sand to a fine surface and blend the topcoat. Optimize cleanroom conditions/extraction to avoid recurring problems.
Are commissioning/audit checklists available?
Safety training (PPE/CLP), process parameter sheet, maintenance plan (filter/resin), test plan (adhesion/gloss/conductivity), traceability (batch/revision).
Latest revisions – where to check?
Always use the documents linked here. Check the revision date at the end of the PDF and replace local copies.
