After Use Storage (Extending Shelf Life)
When stored correctly, our custom-coloured aerosols will remain in excellent condition for up to 24 months after first use.
How to prepare your aerosol for storage:
Turn the can upside down and count slowly to 30.
Press the nozzle while upside down for no more than 6–7 seconds, or until the colour clears and only propellant is released.
Wipe the nozzle clean with a cloth.
Replace the cap securely before storing.
By clearing the valve and nozzle, you prevent blockages and preserve the integrity of the paint.
Paint remains good for at least 24 months if stored correctly.
Canisters themselves are durable for 10+ years.
Why Proper Storage Matters
Custom coloured aerosols contain flammable solvents and liquified petroleum gas (LPG) propellants. Left unprotected, they risk malfunction or even explosion when exposed to extreme heat or flame. Proper storage safeguards both product quality and workplace safety.
Store Safely - Key Guidelines
| Condition | Recommendation |
|---|---|
| Temperature | Store between 5 °C and 25 °C. Avoid exceeding 54 °C, as heat buildup can cause rapid pressure increase and potential canister failure. |
| Environment | Keep cans in cool, well-ventilated areas—away from direct sunlight and heat sources. A fire-proof safety cabinet is ideal for bulk storage. |
| Seal & Clean | Always clean and reseal cans after use to prevent nozzle blockages caused by dried paint residue. |
| Shelf Life | Unopened custom aerosol cans have a long shelf life. After first use, product remains stable for 12–24 months, provided it’s stored and maintained correctly. |
| Documentation | Always refer to the Safety Data Sheet (SDS), Technical Data Sheet (TDS), and product label for specific storage and handling directions. |
Regulatory & Safety Considerations
Aerosol cans are classified as Dangerous Goods (Class 2: UN1950) and may display a red flammable gas or liquid diamond symbol.
In high-risk environments, using fire safety cabinets (up to 250 L capacity) can consolidate and protect aerosol, paint, and corrosive materials—ideally with spill trays and proper separation.
Even under normal conditions, exposure to temperatures above design tolerances—especially over 54°C—can lead to violent rupture or fireball formation.
Disposal & Recycling
Aerosols typically contain 60% tinplated steel and 40% aluminium, making them highly recyclable.
Completely depleted cans may be disposed of via standard recycling streams. However, partially full or pressurised cans are hazardous and must be handled as hazardous waste—either through household hazardous collections or drop-off at local facilities.
Never puncture, crush, or incinerate aerosol cans—this poses a serious explosion risk.
Key Tips for Users
Check storage environment regularly—ensure temperatures stay within safe range and containers remain intact.
Use quickly after opening, and always clean nozzles to avoid drying and blockages.
Dispose responsibly—when unsure, contact local waste management or consult customer service.
