NCS S 1040-B70g Aerosol Spray Paint 400ml Cans

NCS S 1040-B70G Aerosol Spray Paint is a custom-mixed colour from our NCS Aerosol Spray 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.
