SATAjet X 5500 PHASER: High-Gloss Clearcoat with System
This guide focuses on mirror-smooth clearcoat surfaces without orange peel. You’ll get tested reference values, a precise process for gloss and flow, as well as quick solutions for clearcoat-specific problems.
Application Profile & Variants
The PHASER builds on X-nozzle technology and is predestined for clearcoat work – either as HVLP or RP, depending on the desired balance of surface finish and process speed.
| Variant | Clearcoat Suitability | Strengths in Finish |
|---|---|---|
| HVLP | High material efficiency, fine edge control | Very controlled application, minimal overspray |
| RP | Fast layer build-up, high area coverage | Very smooth flow, excellent flatness |
Recommended Clearcoat Nozzles
RP: commonly 1.3; HVLP: commonly 1.4 – depending on material (reference values).
Working Pressure Range
HVLP approx. 2.0 bar; RP approx. 2.2–2.5 bar at the gun (reference values).
Max. Inlet Pressure
Typically 10 bar; remain within recommended working window.
Practical Tip: For mirror-smooth flow in clearcoat, slightly open the material flow regulator further, then fine-tune pressure in 0.1-bar steps and test on a sample panel. This way you’ll find the balance between fullness and flow.
Clearcoat: Basic Settings (Reference Values)
- HVLP: ~2.0 bar; 17–20 cm distance; wide fan; material 1.5–2 turns.
- RP: ~2.3–2.5 bar; 18–22 cm distance; wide fan; material 1.25–1.75 turns.
- Nozzle: HVLP often 1.4; RP often 1.3 – depends on viscosity and system.
- Overlap: ~70–75% for even layer build without dry edges.
Always consider the paint manufacturer’s specifications and the environment (temperature/humidity).
High-Gloss Process (6 Steps)
- Dust off and degrease part; carefully mask edges and transitions.
- Select the right nozzle, set pressure; prepare a test panel for flow/gloss.
- Apply the first layer of clearcoat thinly and evenly; align the fan cleanly.
- After flash-off, apply the second layer with slightly increased material flow for a “wet-on-wet” flow.
- Guide critical zones (edges/borders) with consistent distance, avoid overloading.
- Check the finish; if needed, polish out dust inclusions locally after drying.
Clearcoat: Quick Fixes
Orange Peel
- Slightly increase pressure, stabilize fan.
- Reduce viscosity; consider temperature.
- More consistent gun movement, constant overlap.
Runs/Sags
- Slightly reduce material flow.
- Try a one-size smaller nozzle or increase distance.
- Strictly observe flash-off times.
Dry Edges
- Lower pressure slightly; wet edge zones first.
- Reduce distance slightly; increase overlap.
- Adjust spray direction to room airflow.
Unstable Fan
- Thoroughly clean and correctly mount air cap/nozzle.
- Check strainer/cup for blockage.
- Open air regulator, fine-tune pressure.
Maintenance & Service
- After use: clean material channels, nozzle, and air cap immediately.
- Check seals, needle, and springs regularly and replace if needed.
- Use only suitable cleaning agents; no hard tools.
- Lightly grease threads; protect O-rings from solvents.
- Store dry and dust-free; keep cup clean separately.
FAQ: Clearcoat with the PHASER
Which nozzle for high-gloss flow?
Often 1.3 (RP) or 1.4 (HVLP); align with viscosity/manufacturer data.
How do I stabilize gloss level?
Maintain constant distance, overlap ~70–75%, fine-tune pressure in small steps.
Can I process water- and solvent-based clearcoats?
Yes, with a suitable nozzle and thorough cleaning/material compatibility.
Is there a maximum pressure?
Typically 10 bar inlet pressure; stay within working ranges.
How do I prevent dust inclusions?
Dust off part and environment, ensure clean airflow, clean the air cap in between.
Conclusion
For high-gloss clearcoat, the PHASER plays to its strengths: stable fan, reproducible flow, and finely adjustable material delivery. With the reference values and process above, you’ll reliably achieve a brilliant, level gloss.
