Technical overview of Master Chroma CR3630 - Red 3630 Aerosol Spray Paint

Master Chroma CR3630 - Red 3630 Aerosol Spray Paint is a custom-mixed colour from our Master Chroma Aerosol Spray 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.

Frequently Asked Questions

Master Chroma CR3630 - Red 3630 Aerosol Spray Paint is a custom-mixed colour from our Master Chroma 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.
