Technical overview of Master Chroma Isofan - N9273 - Neutral Aerosol Spray Paint

Master Chroma Isofan - N9273 - Neutral Aerosol Spray Paint is a custom-mixed colour from our Master Chroma Isofan Paint chart, available as 1K (ready to use), 2K (integrated hardener for higher chemical and abrasion resistance) and 2K Air-Dry (non-isocyanate hardener). Finishes: Matt 0%, Satin 30%, Semi 60%, Full Gloss 90%. 2K aerosols are supplied as Acrylic Enamel only.

Surface preparation standards (plastics, metals, wood, uPVC)

Clean/degrease thoroughly, then key the surface (typical P400–P600 for plastics/metals). Use substrate-appropriate primers: plastic adhesion for plastics/uPVC; etch/anti-corrosive for bare metals; sealers/primers for wood; dedicated systems for glass/fibreglass. Correct priming improves adhesion and durability.

Application parameters (distance, passes, overlap, flash-off)

Spray at ~15–25 cm with steady speed and angle. Apply light, even passes with ~50% overlap. Flash-off: 1K ~5–10 minutes, 2K ~10–15 minutes depending on conditions. Use adjustable fan width to suit the area and limit overspray.

Recoat window and curing schedule (1K vs 2K)

1K: recoat after about 10–15 minutes; typical handling cure around 30 minutes. 2K: recoat after about 20–30 minutes; touch-dry roughly 40 minutes; full cure around 24–48 hours. Ambient conditions will affect all timings.

Coverage and target film build

Guide coverage is around 2 m² per coat from a 400 ml aerosol on a smooth, primed substrate. Plan for 2–4 light coats. Target around 20–40 µm total dry film thickness; a light aerosol pass can deposit roughly 10–15 µm depending on technique and conditions.

System compatibility (primers, clears, overcoating)

Use compatible primers and clears from the same system where possible. Avoid mixing dissimilar chemistries without testing. Respect recoat windows to protect intercoat adhesion and gloss. Always validate with a small test area.

Environmental conditions and safety

Apply in mild, dry conditions—ideally 10–25 °C with relative humidity under 75% and steady airflow. Keep the substrate at least ~3 °C above dew point. Use appropriate PPE (respirator, gloves, eye protection) and ensure excellent ventilation. Refer to the product data sheets for full guidance.

Trade Application Notes

Master Chroma Isofan - N9273 - Neutral is part of our Master Chroma Isofan Paint Colour Chart. Each order is mixed fresh using Lechler binders and colourants, so follow on orders are designed to sit neatly alongside earlier work for touch ins, snagging and small repairs.

Formats: 400 ml aerosols in 1K (ready to use), 2K (with integrated hardener) or 2K Air Dry, plus 1 litre tins, touch up pots and pens for fine detail and small areas.
Finishes: Matt, satin, semi gloss and full gloss options so you can match existing schemes, client specification or a particular maintenance schedule.
Surface preparation: For the best result we suggest degreasing, lightly abrading to a uniform key and carefully removing dust. Please choose a suitable primer for the substrate and environment.
Masking and protection: It is a good idea to protect nearby glazing, brickwork, signage and floor surfaces. Simple masking and sheeting can greatly reduce clean up time on busy sites.
Application control: The vari nozzle cap can be set to a wider or narrower fan pattern to suit the job. This helps with gentle edge control and can reduce unwanted overspray.
Overspray awareness: On external work it helps to think about wind direction and people passing close by. Temporary screens and a clear working zone can make application more relaxed.
Weather window: Choose a dry, clean surface and avoid conditions where rain or condensation are likely. Please follow the temperature and humidity guidance in the product data sheet.
Recoat and curing: Several lighter coats with the recommended flash off time usually give a smoother, more even finish. Allow time for full cure before any heavy cleaning or handling.
2K products: 2K materials are for professional use and are best applied with suitable PPE and good ventilation. Mix carefully, respect pot life and dispose of any waste responsibly.
Equipment: Aerosol cans will usually perform better if kept at room temperature and shaken well before use. Tins can be applied using compliant spray equipment or with a fine foam roller and brush for edges.
Coverage and appearance: Gentle, even passes allow the colour and sheen to build gradually, helping to avoid runs, dry spray patches and patchy gloss levels.
Aftercare: Once coated, try to keep the surface free from tape pull, impact and aggressive wash down until the coating has had time to harden. Simple, mild cleaning products are usually sufficient.
Repeat orders: Batch information can be recorded so that future top ups can be mixed to the same colour and finish, helping return visits feel calm and predictable.

When paired with the correct primer this system can be suitable for many common substrates, including metal, correctly prepared plastics and timber. The aim is a smooth, reliable finish with good adhesion and stable colour under normal service conditions.

Frequently Asked Questions

Master Chroma Isofan - N9273 - Neutral Aerosol Spray Paint is a custom-mixed colour from our Master Chroma Isofan Paint chart, available as:

1K aerosol/tin: ready to use; general purpose.
2K aerosol/tin: integrated hardener for higher chemical/abrasion resistance.
2K Air-Dry: 2K performance with non-isocyanate hardener for easier handling.

Finishes: Matt 0%, Satin 30%, Semi 60%, Full Gloss 90%. 2K aerosols are supplied as Acrylic Enamel only.

Clean/degrease: remove oils, silicones and residues (use panel-wipe; lint-free cloths).
Key the surface: typical aerosol prep is P400–P600 (plastics/metals), vacuum then tack-rag.
Primers: plastic adhesion for plastics/uPVC; etch/anti-corrosive for bare metals; sealers/primers for wood; dedicated systems for glass/fibreglass.

Correct priming vastly improves adhesion, opacity and long-term durability.

Spray distance: ~15–25 cm; maintain a constant angle and speed.
Technique: light, even passes with ~50% overlap; build film gradually.
Flash-off between light coats: 1K ~5–10 mins; 2K ~10–15 mins (conditions dependent).
Nozzle control: use the vari-nozzle (wide/narrow) to suit area and reduce overspray.

Always test on a small area to validate settings before full application.

1K: recoat ~10–15 mins; typical handling cure ~30 mins.
2K: recoat ~20–30 mins; touch-dry ~40 mins; full cure ~24–48 hrs.

Temperature, airflow and humidity significantly affect all timings—verify on your substrate.

Coverage guide: ~2 m² per coat from a 400 ml aerosol on a smooth, primed substrate.
Typical passes: 2–4 light coats for uniform colour and gloss.
Film build: plan for ~20–40 µm DFT across the system; a light aerosol pass can deposit ~10–15 µm (approx.).

Heavily textured/porous surfaces and strong colour changes may require additional coats.

Use system-appropriate primers and clears from the same family where possible.
Avoid mixing dissimilar chemistries without testing; perform a small adhesion/solvent-rub test first.
Observe recoat windows to protect intercoat adhesion and gloss.

For detailed guidance, refer to the data sheets below.

Ambient: ideally 10–25 °C, RH < 75%, steady airflow; substrate temperature at least ~3 °C above dew point.
PPE: suitable respirator, gloves, eye protection; ensure excellent ventilation.

See data sheets: 1K · 2K/2K Air-Dry.

Please note: our paint is custom mixed and should be test-sprayed on a small, inconspicuous area before full application. We cannot accept responsibility for any colour difference once paint has been applied to your surfaces. If the colour is not accurate, please contact us to arrange a return.
